Developing Device and Image Forming Apparatus

摘要

A developing device and an image forming apparatus including the developing device are provided. The developing device includes a housing, a developer carrier which is rotatably supported by the housing, and which carries developer on a circumferential surface thereof, a layer thickness regulating member which includes, a blade contacting the circumferential surface of the developer carrier along a rotational axial direction of the developer carrier, and a support member supporting the blade, the layer thickness regulating member for regulating a layer thickness of the developer on the circumferential surface of the developer carrier. The support member includes: a contact part which contacts the blade; and a pair of attachment parts which are attached to the housing. The attachment parts are provide at both sides of the contact part in the rotational axial direction and are further protruded than the contact part in a direction away from the developer carrier.

主权项

1. A developer cartridge comprising:
a housing configured to accommodate developer therein; a developing roller rotatable about an axis extending in a first direction; a blade configured to regulate a thickness of the developer on a circumferential surface of the developing roller, the blade extending in a second direction, the blade having a first end in the second direction and a second end separated from the first end in the second direction, the first end being closer to the circumferential surface of the developing roller than the second end; and a support member extending in the first direction, the support member supporting the blade, the support member having a third end in the first direction and a fourth end separated from the third end in the first direction, the support member including:
a first protrusion protruding from the third end in the second direction, the first protrusion having a first hole;a second protrusion protruding from the fourth end in the second direction, the second protrusion having a second hole;a first screw inserted into the first hole, the first screw attaching the first protrusion to the housing; anda second screw inserted into the second hole, the second screw attaching the second protrusion to the housing.
