Abstract
Official abstract text for this publication.
In a developing device, a layer thickness regulating member, configured to regulate thickness of a layer of developer borne on a surface of a developer bearing member, includes: a first plate-shaped member having a pair of opposite ends in a perpendicular direction perpendicular to an axial direction of the developer bearing member, one end in the pair of opposite ends being in contact with the developer bearing member, the other end being supported by the casing; and a second plate-shaped member that is fixedly secured to the casing and that supports the first plate-shaped member. A seal member, which is in contact with an end portion of the developer bearing member in the axial direction of the developer bearing member, is in contact with an end portion of the first plate-shaped member in the axial direction of the developer bearing member. The second plate-shaped member holds the seal member.
First claim
Opening claim text (preview).
What is claimed is: 1. A developing device comprising: a casing configured to accommodate developer therein; a developer bearing member mounted in the casing so as to be rotatable about its axis and configured to bear developer thereon; a layer thickness regulating member mounted in the casing and configured to regulate thickness of a layer of developer borne on a surface of the developer bearing member; and a seal member that is in contact with an end portion of the develop…
