Abstract:
1. A developer regulating member, which comprises a plate-like member made of an elastic metallic material and having a bent portion bent at a predetermined curvature radius, and which causes a surface of the bent portion to abut against a surface of a developer carrier so that an edge line of the bent portion intersects at right angles with a direction of surface movement of the developer carrier, to thereby regulate the thickness of a developer on the developer carrier, wherein the plate thickness of the plate-like member is at least 60 [μm] but less than 150 [μm], and wherein when the curvature radius is represented as R [μm] and an average crystal particle diameter of the plate-like member is represented as D [μm], the curvature radius R and the average crystal particle diameter D satisfy the following expression (1):
