Abstract

A developing device includes: a developer bearing body for bearing liquid developer, the liquid developer bore by the developer bearing body being used by the developing device to develop a latent image bore by an image bearing body; a developer supplying member that has depressions in its surface and whose surface is pressed in contact with the developer bearing body for supplying the liquid developer retained in the depressions to the developer bearing body; and a restricting section for restricting the amount of the liquid developer on the developer supplying member, wherein the amount of the liquid developer, which is retained in the depressions and whose amount has been restricted by the restricting section, before being supplied to the developer bearing body is smaller than the volumetric capacity of the depressions that retain the liquid developer.
