A thin layer of developer is formed on a developer carrier, and by applying a high frequency alternating voltage to the developer carrier, the thin layer of developer is caused to fly onto the electrostatic latent image carrier, thereby forming an electrostatic latent image. 1. A one-component developing device for producing a visible image, characterized in that the waveform of the high-frequency alternating voltage is set asymmetrically with respect to a time axis. (2) The waveform of the high-frequency alternating voltage has a time period of T 1 during which the developer is applied in the direction in which the developer flies from the developer carrier to the electrostatic latent image carrier, and a period of time T 1 for developing the developer from the electrostatic latent image carrier to the developer carrier. The one-component developing device according to claim 1, wherein T 1 >T 2 is set, where T 2 is the time during which the agent is applied in the direction in which the agent is returned. (3) The relationship T 1 > T 2 is 1.5≦T 1 /
The one-component developing device according to claim 2, wherein T 2 ≦5.
