Abstract
An image recording unit is provided with a developing bias voltage output circuit for outputting a developing bias voltage to a developing unit, to thereby cause the developing unit to develop, using toner, an electrostatic latent image, formed on an electrically-charged body, into a visible toner image. A CPU serves to output a developing bias voltage control signal to a developing bias voltage varying circuit. The CPU outputs a developing bias voltage control signal based on manual key operations performed by a user. In response to the developing bias voltage control signal, the developing bias voltage varying circuit controls the developing bias voltage output circuit to change the developing bias voltage to be outputted therefrom.
