Abstract
A single-component developing apparatus comprising a developer holding member having a peripheral surface, a power supply section applying an AC developing bias voltage to the developer holding member, the AC developing bias voltage having a waveform with predetermined minimum value, maximum value and period, an electrostatic latent image receiving member opposing the developer holding member across a gap having predetermined width, a developer supplying section supplying a developer to the developer holding member, and a developer regulating member forming developer into a thin layer on the peripheral surface of the developer holding member by pressing on the developer holding member. In this arrangement the developer holding member transports the thin layer of developer towards the electrostatic latent image receiving member, and the transported thin layer of developer flies from the developer holding member across the gap to the electrostatic latent image receiving member in accordance with the AC developing bias voltage. The waveform of the AC developing bias voltage satisfies the inequality:
