Abstract

PURPOSE:To automatically adjust measurement of the toner concentration by measuring the toner concentration at the time of detecting that stored contents of a log storage means is a prescribed value and adjusting a toner concentration measuring means so that the result of comparison between the measured result and a reference value is equalized. CONSTITUTION:A discrimination number reading means 14 reads the discrimination number of a set developing device 11 and the discrimination number is stored in a discrimination number storage means 15. A control means 21 stores the log of the number of times of image formation in a log storage means 16 in accordance with the discrimination number stored in the means 15. If stored contents of the means 16 are zero, the means 21 adjusts a toner concentration measuring means 17 by an adjusting means 19. The adjustment value of the means 19 is stored by an adjustment storage means 20. After the means 17 is adjusted in this manner, the toner concentration of a developer is measured by the means 17, and the measured result is compared with the reference value by a comparing means 18, and the comparison result is sent to the means 21. The means 21 operates a toner replenishing means 13 in accordance with the comparison result of the means 18 to control due toner concentration of the developer.
