ABSTRACT:
An image forming apparatus includes a plurality of color toner development devices, a recycled toner development device, at least one cleaning device, a toner collecting and supplying device, and an image pattern generation device. The plurality of color toner development devices store separate color toners, and the recycled toner development device stores recycled toner. The at least one cleaning device removes toner remaining on at least one image carrying member after a transfer operation. The toner collecting and supplying device stores and supplies the removed toner to the recycled toner development device. The image pattern generation device generates image patterns developed by the plurality of color toner development devices and the recycled toner development device based on a characteristic of developer and a color of the recycled toner stored in the recycled toner development device.
