An object of the present invention is to provide an image reading device having a highly convenient toner ink removing function and an image processing device (a facsimile, an electronic filing device, a multifunction device, etc.) provided with the image reading device.

In order to solve the above-mentioned problems, the present invention provides an apparatus capable of performing a target reading and a toner ink removing process by a single setting operation as described later. The solution is to solve the problem, but the following 1. It is another object of the present invention to solve the above problem. 1. When the image reading device and the toner ink removing device are simply combined and connected, the document that has failed in the reading operation may also remove the toner ink and lose image information during processing. 2. Even if the reading operation is completed normally, the image information may be deficient in the result due to a setting error of the reading condition or the like. As a result, necessary information may be lost, and improvement is required. 3. If a normal operation is performed when a blank document is to be processed, the unprinted blank document also removes the toner ink, resulting in wasteful processing and environmental (power consumption) considerations. Also need improvement. 4. If the front / back is wrong when setting the original, or if the front / back are mixed, the back original will not be processed,
Once the processing of all originals is completed, the document is inverted again and re-executed, so that it is inconvenient to use and needs improvement.
