The following describes the operation of the present invention.

First, as shown in FIG. 5, the waste toner mixed with the magnetic toner and the non-magnetic toner is supplied to the toner separation unit 120 through the supply unit 110, and the waste toner through the supply unit 110 is an airflow feeder. The toner separation unit 120 is supplied to the toner separation unit 120 by an airflow supplied from an illustration (not shown).

When the waste toner supplied to the toner separator 120 is supplied to the magnetic roller 121 which rotates the magnetic force to another one or more, the magnetic toner of the waste toner supplied to the first magnetic roller 121a having a predetermined magnetic force is The magnetic toner attached to the first magnetic roller 121a and rotated at the same time as the first magnetic roller 121a is rotated is transferred to the second magnetic roller 121b having a stronger magnetic force than the first magnetic roller 121a. .

At this time, the first and second magnetic rollers 121a and 121b are adjacent at intervals of 2 to 20 mm, and the magnetic force of the second magnetic roller 121b is larger than that of the first magnetic roller 121a. The magnetic toner attached to the surface of the first magnetic roller 121a can be easily transferred to the second magnetic roller 121b.

Here, the first and second magnetic rollers (121a, 121b) is a form in which the permanent magnets of the N pole and the S pole radially inserted into the cylindrical body of stainless steel, the magnetic force is different from the first magnetic pole 2, When the magnetic rollers 121a and 121b rotate, the magnetic force and repulsive force act at the proximal portions of the two rollers so that the magnetic toner attached to the surface of the first magnetic roller 121a and a small amount of nonmagnetic toner are applied. As the position shift occurs, the magnetic toner is easily transferred to the second magnetic roller 121b, and a small amount of non-magnetic toner is attached to the surface of the first magnetic roller 121a to meet the waste toner of the supply unit 110.

The magnetic toner transferred to the second magnetic roller 121b is separated from the surface of the second magnetic roller 121b while being caught by the scraping blade 121 'which is in surface contact with one side of the second magnetic roller 121b. The magnetic toner caught by the lowering blade 121 'is separated from the lowering blade 121' by the rotation of the scraping down rotation roller 123, and is moved to the first recovery guide 130.

In addition, the magnetic toner of the waste toner supplied to the toner separator 120 through the supply unit 110 is attached to the magnetic roller 121 and moved, and the non-magnetic toner of the waste toner is connected to the magnetic roller 121. It falls to its own weight without being attached, which is moved to the second recovery guide 130 'while being scattered by the air supplied to the air hole 122 by the air supplier (not shown).

Here, as shown in FIG. 5, the air hole 122 may be formed to be inclined upwardly from the bottom of the magnetic roller 121, and as shown in FIG. 8, the magnetic roller 121 and the center thereof may be formed. It may be formed to be inclined so as to face from the top to the bottom in line with the axis.

In the above process, the magnetic toner and the non-magnetic toner, which are respectively moved to the first and second recovery guides 130 and 130 ', are collected and stored in the guide tubes 131 and 131', and at the same time, the guide tubes 131 ( 131 '), the magnetic toner and the non-magnetic toner are released by the rotation of the agitator 132, 132', and discharged to the guide tubes 131 and 131 '. As the (133) and (133 ') are rotated, they are seated on the belts (141) and (141') of the magnetic / non-magnetic toner collecting parts (140, 140 ').

The magnetic toner and the non-magnetic toner seated on the belts 141 and 141 'may be moved by the rotation of the rotary rollers 142 and 142', as well as the belts 141 and 141. Heat generated from the heating members 143 and 143 'is applied to the magnetic toner and the non-magnetic toner seated on') to evaporate the moisture contained in the magnetic toner and the non-magnetic toner.

At this time, the heating members 143 and 143 'evaporate moisture contained in the magnetic toner and the non-magnetic toner while maintaining a temperature of 40 to 45 ° C., and the heating members 143 and 143 ′ are 50 ° C. or more. When heat is applied, it is undesirable to maintain a high heat of 50 ° C. or higher because the toner aggregates and results in poor fluidity.

The magnetic toner and the non-magnetic toner evaporated by the heat of the heating members 143 and 143 'are rotated in the direction of the magnetic / non-magnetic toner collecting members 144 and 144' by the rotation of the belts 141 and 141 '. When placed above the magnetic / non-magnetic toner collecting members 144 and 144 ', the magnetic toner is moved by brush rollers 145 and 145' which rotate in surface contact with the belts 141 and 141 '. The non-magnetic toner is collected from the magnetic / nonmagnetic toner collecting members 144 and 144 'away from the belts 141 and 141'.

Moisture contained in the magnetic toner and the non-magnetic toner has a low electrical resistance, thereby affecting the triboelectric chargeability, and causing a problem of contaminating the background by making the development or the transfer process unsatisfactory. It is a cause of poor cleaning and cleaning properties, and increases the softening temperature of the toner powder, thereby preventing the sticking to the transfer target. Therefore, the heating members 143 and 143 'are contained in the magnetic toner and the non-magnetic toner. Water must be removed.

In the above process, the magnetic toner and the non-magnetic toner which have been dehydrated may be used by adding an additive of a flow improver and a toner modifier, but the magnetic toner and the non-magnetic toner may be used in order to obtain high precision and high image quality. It is preferable to separate the contained impurities.

As the magnetic toner and non-magnetic toner collected in the magnetic / non-magnetic toner recovery unit 140 and 140 'are removed by the above process, the magnetic / non-magnetic toner forming unit is shown in FIGS. It is supplied to each of the 150 and 150 ′ to remove impurities.

The magnetic toner and the non-magnetic toner collected in the magnetic / non-magnetic toner recovery unit 140 and 140 'are supplied to the hoppers 151 and 151' of the magnetic / non-magnetic toner forming unit 150 and 150 '. Since the hoppers 151 and 151 'have a narrower outlet than the inlet, the magnetic toner and the non-magnetic toner are stacked and stacked from the lower end of the hopper 151 and 151'. The non-magnetic toner has a fluidity and can not move to the exit, but also becomes stagnant. As a result, an empty space is formed at the portion where the magnetic toner and the non-magnetic toner exit the outlet, so as to prevent the phenomenon, at the lower end of the hopper 151, 151 '. Scratch or touch the magnetic toner and nonmagnetic toner near the top of the agitator 152 and 152 'with the rotation of the located agitator 152 and 152' to fill the empty space by improving the fluidity, and the hopper 151 Discharged at the same time as 151 ') The toner and the non-magnetic toner are rotated by being attached to the surfaces of the rotating feed rollers 153 and 153 '.

At this time, a doctor blade (B) having a thickness of 1 to 2 mm is disposed between the hopper 151 and the supply roller 153 and between 0.2 and 0.2 mm as a metal plate between the hopper 151 'and the supply roller 153'. The 0.5mm thick doctor blade (B ') is positioned so that the magnetic toner and the non-magnetic toner are always uniformly attached to the supply rollers (153) (153') at the contact pressure of the doctor blade (B) (B '). To the photosensitive drums 154 and 154 '.

In addition, the supply rollers 153 and 153 'are supplied with a developing bias in which a DC voltage of -300 to -350 V and an alternating electric field are superimposed by a power supply (not shown) and supplied with the supply rollers 153 and 153'. The exposure is developed on the surface of the irradiated photosensitive drum 154 (154 ') while keeping the interval of 200-300 mu m.

Here, the surface of the feed rollers 153 and 153 'which are not developed in the process of developing the magnetic toner and the non-magnetic toner to the photosensitive drums 154 and 154' by the feed rollers 153 and 153 '. The traces of the powder or the unreacted reactant impurities remaining in the are removed from the surface of the feed rollers 153 and 153 'by the cleaning blades 157 and 157' as well as the impurity collecting members 158 and 158 '. Are collected off.

Here, the magnetic toner caught by the cleaning blade 157 is separated from the cleaning blade 157 by the rotation of the scraping roller 159 and is collected in the impurity collecting member 158.

Prior to the development of the magnetic toner and the non-magnetic toner attached to the supply rollers 153 and 153 'to the photosensitive drums 154 and 154', the charging step and the exposure step are performed. The drums 154 and 154 ', and the photosensitive drums 154 and 154' are electrostatically charged below -700 to -900V by a charging roller, and then laser light is emitted by the laser beam scanner. And widely exposed to the surface of the photosensitive drums 154 and 154 '.

The photosensitive drums 154 and 154 'exposed to a wide surface as described above are rotated in a state in which an electrostatic latent image is formed, and the magnetic toner and non-magnetic toner attached to the supply rollers 153 and 153' are exposed to the photosensitive drum 154. The magnetic toner and the non-magnetic toner attached to the surface of 154 'in large quantities are separated from the surface of the photosensitive drums 154 and 154' by the scraping blades 156 and 156 ', and at the same time, the collecting member 155 155 '.

In the above process, an additive of a flow improver and a toner modifier is added to the magnetic toner and the non-magnetic toner from which impurities are extracted. The flow improver is added in an amount of 0.1 to 4.0 wt% based on the total weight of the magnetic toner and the non-magnetic toner. The toner modifier is added in an amount of 0.1 to 5.0 wt% based on the total weight of the magnetic toner and the non-magnetic toner.

The flow improver mixes inorganic fine powder having an average particle diameter of 20 to 50 nm, and the inorganic fine powder improves the fluidity of the magnetic toner and the non-magnetic toner, and adjusts the amount of charge to uniformly charge the particles while maintaining environmental safety. Gives a good function.

The inorganic fine powder is any one of fine silica powder, fine titanium oxide powder, fine alumina powder, and the addition ratio thereof is preferably added at 0.1 to 4.0 wt% based on the total weight of the magnetic toner and the nonmagnetic toner. This is because, when added in less than 0.1% by weight, it is difficult to obtain the effect, and when more than 4.0% by weight may cause fixing performance and other functional degradation.

The toner modifier adds a conductive fine powder having an average particle diameter smaller than that of the toner, the conductive fine powder being a non-magnetic white or pale powder zinc to improve developing performance and maintain high image density and to increase charging performance. Fine powders of organic oxides such as oxides, tin oxides and titanium oxides are preferably 0.1 to 5.0% by weight based on the total weight of the magnetic toner and the nonmagnetic toner, which is less effective when added below 0.1% by weight. This is because it is difficult, and when it is 5.0 wt% or more, it may cause a decrease in its function.

In the above process, the magnetic toner and the non-magnetic toner, which are regenerated by mixing the additives of the flow improver and the toner modifier to the magnetic toner and the non-magnetic toner, from which impurities are removed, are mixed with a mixer (not shown).
