Abstract

A layer thickness regulating member includes: an opposing portion having an opposing surface to a peripheral surface of a developer carrying member; and a layer thickness regulating portion, projected from the opposing surface toward the developer carrying member, for regulating a layer thickness of a developer carried on the developer carrying member. The layer thickness regulating portion is integrally molded with the opposing portion. The layer thickness regulating member is, after being molded in a metal mold, separated by being pushed from a side opposite from the opposing portion of the layer thickness regulating member when the layer thickness regulating member is separated from the metal mold.

Claims (8)

1. A layer thickness regulating member comprising:

a base portion;

a layer thickness regulating portion, projected from a front side surface of the base portion, configured to regulate a layer thickness of a developer; and

a reinforcing rib portion, projected in a rear side of the base portion, formed along a longitudinal direction of the layer thickness regulating member,

wherein the layer thickness regulating portion and the reinforcing rib portion are integrally molded with the base portion,

wherein the layer thickness regulating portion is separated from a metal mold by pushing out a free end of the reinforcing rib portion from a rear side of the base portion by a plurality of pushing-out members after being metal-molded, and

wherein a molding trace by the plurality of pushing-out members is formed on a surface of the free end of the reinforcing rib portion.

2. The layer thickness regulating member according to claim 1 , wherein the reinforcing rib portion is provided at a non-overlapping position with a position corresponding to a position where the layer thickness regulating portion is provided.
