Developing device

摘要

A developing device is provided. The developing device includes a housing, a developer carrier which is rotatably supported by the housing, and a layer thickness regulating member which includes a blade configured to contact the developer carrier along a rotational axial direction of the developer carrier, a support member supporting the blade, and a reinforcement member provided at an opposite side to the support member with respect to the blade and reinforcing the blade. The support member includes a first part which contacts the blade, and to which the blade is fixed, a second part which is connected to the reinforcement member, and a third part which is attached to the housing. As viewed from the rotational axial direction, the first part and the third part are provided on a same first plane, and the second part is provided on a second plane intersecting with the first plane.

主权项

1. A developing device comprising:
a housing; a developing roller; a layer thickness regulating member including:
a blade which contacts a circumferential surface of the developing roller at a contact portion of the blade along a rotational axial direction of the developing roller;a support member which supports the blade; anda reinforcement member which contacts the blade and the support member, wherein the support member includes:
a first plate which contacts the blade;a second plate extending in a first direction orthogonal to the first plate;an attachment part which is attached to the housing, and wherein the reinforcement member includes:
a third plate which contacts the blade to sandwich the blade with the first plate; anda fourth plate which is fixed to the second plate, the fourth plate extending in the first direction, wherein as viewed from the rotational axial direction, a surface of the first plate and a surface of the attachment part are provided on a same first flat plane, and a surface of the second plate is provided on a second flat plane, the second flat plane being provided between the attachment part and the contact portion.
