ABSTRACT:
An image forming apparatus is used, in which an electrostatic image formed on a moving image forming belt is developed by AC development. Where the image forming belt moves at a speed of v.sub.p mm/s, the cleaning potential is V.sub.cl volts, and the AC bias frequency is f kHz, the function Z satisfies the following equation: ##EQU1## Images substantially free of background development are thereby obtained.
