ABSTRACT:
A liquid developer apparatus comprises a developer unit for applying a liquid developer to an electrostatic latent image formed on a recording medium, and a switch circuit for selectively outputting to the developer unit one of a first bias voltage and a second bias voltage which has the same polarity as that of the electrostatic latent image and is higher than the first bias voltage. The switch circuit outputs the second bias voltage during a predetermined period of time other than a period of time in which the electrostatic latent image is developed.
