DEVELOPING APPARATUS, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

摘要

A developing apparatus in which a developer bearing member rotates in a first rotational direction, a stirring member rotates in a second rotational direction opposite to the first rotational direction, and, in a contact region where the stirring member and the development bearing member contact each other, a moving speed of the developer bearing member is higher than a moving speed of the stirring member.

主权项

1. A developing apparatus comprising:
a developer bearing member configured to bear a developer and rotate to apply the developer to an image bearing member to perform image forming; and a stirring member, having (1) a rotating rotary member and (2) a flexible sheet member attached to the rotary member, configured to stir a developer, a free end of the sheet member being capable of contacting a surface of the developer bearing member in an image forming region, wherein the developer bearing member rotates in a first rotational direction, wherein the stirring member rotates in a second rotational direction which is opposite to the first rotational direction, and wherein, in a contact region where the stirring member and the development bearing member contact each other, a moving speed of the developer bearing member is higher than a moving speed of the stirring member.
