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.
