摘要： In an image forming apparatus that uses toners of a plurality of different colors, amorphous toner is used during image forming with a first color. Then, a controller, by using a toner remaining-removing switching device, causes toner scraped off from an image carrier by a blade during cleaning to remain at a predetermined region near the blade. Spherical toner is used during image forming with a second color and thereafter. The controller switches the toner remaining-removing switching device during any one of processes starting from the process of the second color until the end of image formation to remove toner remaining at the predetermined region, and the toner subsequently scraped off, from the image carrier.
