Abstract (en)
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 vp mm/s, the cleaning potential defined as the absolute value of the difference between the potential of the non-image areas and the DC bias potential is Vcl volts, and the AC bias frequency is f kHz, the function Z satisfies the following equation: <MATH> Images substantially free of background development are thereby obtained.
