装置。[Scope of Claim for Utility Model Registration] (1) A developer carrier that uses a microcapsule developer consisting of a core material and an outer shell and contains magnetic powder, and that faces an electrostatic latent image carrier, and a developer carrier. In a microcapsule developer developing device comprising a developer regulating member that presses against the developer carrier to regulate the developer on the body surface into a uniform thin layer, the regulating member is attached to the tip of the resin plate. 1. A developing device comprising an elastic member, the free end of which is pressed against a developer carrier at a contact pressure of 20 g/cm or less so as to face the developer carrier in the rotating direction. (2) The developing device according to claim 1, wherein the deflection angle of the regulating member when pressed against the developer carrier is set to 0° to 90°. (3) The developing device according to claim 1, wherein the length from the contact position of the regulating member and the developer carrier to the free end of the regulating member is 0 to 10 mm.
