Abstract:
1. A developing device comprising: a developer hearing body for bearing liquid developer, said liquid developer bore by said developer hearing body being used by said 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 said developer bearing body for supplying the liquid developer retained in said depressions to said developer bearing body; and a restricting section for restricting the amount of said liquid developer on said developer supplying member, wherein the amount of said liquid developer, which is retained in said depressions and whose amount has been restricted by said restricting section, before being supplied to said developer bearing body is smaller than the volumetric capacity of said depressions that retain said liquid developer, wherein said developer bearing body is a developing roller and said developer supplying member is a developer supplying roller, wherein said restricting section is a restriction blade that abuts against the surface of said developer supplying roller to restrict the amount of said liquid developer on said developer supplying roller, wherein said developing roller has an elastic section and said surface of said developer supplying roller is pressed in contact with said elastic section to supply said liquid developer to said developer roller, and wherein the hardness of an abutting section of said restriction blade where said restriction blade abuts against said surface of said developer supplying roller is smaller than the hardness of a press-contact section of said elastic section where said elastic section is pressed in contact with said surface of said developer supply roller.
