ABSTRACT:
In an image forming apparatus including a revolver type developing unit, a cover member surrounds a plurality of developing sections arranged on the developing unit. The cover member is formed with an opening at a developing position facing a photoconductive belt or similar image carrier, and ribs extending in the axial direction of a rotary shaft around which the developing sections are arranged. The cover member therefore deforms little and protects developing rollers and other constituents of the developing unit from damage while causing a minimum of toner to fly about.
