摘要： 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:t.sub.A /T.ltoreq.0.4wherein t.sub.A is rise time from minimum value to maximum value, and T is the period.

摘要： A device for developing an electrostatic latent image recorded on a photoconductive layer. The developing device comprises a doner roll for supporting a uniform layer of single-component developing material adjacent to the photoconductive layer. The doner roll is disposed as to create a space gap between the photoconductive layer and the doner roll. The doner roll is made of semiconductive material having a specific resistance ranging from 10.sup.6 to 10.sup.12 .OMEGA.cm. An electrical bias potential is applied across the gap, thereby establishing a field for transferring the developing material from the doner roll to the photoconductive layer.
