Abstract
A method of forming an image includes the steps of providing a development bias having a DC component and an AC component superposed on one another and applying the development bias to a developer carrying member. The AC component is provided by superposing a waveform at a second frequency on a waveform at a first frequency in synchronism with each other. The second frequency is an odd multiple of the first frequency.
