CARTRIDGES INCLUDING DETECTION MEMBER AND COVER MEMBER

摘要

Cartridges may include a developing roller, an electrode, a detection member, and a cover member. The developing roller rotates about an axis extending along a first direction. The electrode includes a protrusion that protrudes along the first direction to an end portion. The detection member includes a cover portion, which covers an exposable portion of the protrusion when the detection member is in a first position, and which exposes the exposable portion of the protrusion when the detection member is in a second position. The cover member covers a portion of the detection member and exposes the cover portion when the detection member is in the first position. The cover member extends in the first direction to an end portion. An overlap portion of the protrusion extends at least to the end portion of the cover member and overlaps a portion of the cover member in a second direction.

主权项

1. A cartridge comprising:
a developing roller configured to rotate about a first axis extending along a first direction; an electrode configured to electrically connect to the developing roller, the electrode comprising:
a main body; anda protrusion protruding along the first direction from the main body to an end portion of the protrusion; a detection member that is rotatably supported on the protrusion, the detection member comprising a cover portion configured to cover an exposable portion of the protrusion when the detection member is in a first rotational position and to expose the exposable portion of the protrusion when the detection member is in a second rotational position; and a cover member configured to cover a portion of the detection member, the cover member forming an opening therein that is configured to expose the cover portion of the detection member when the detection member is in the first rotational position, and the cover member extending along the first direction to an end portion of the cover member, wherein an overlap portion of the end portion of the protrusion extends at least to the end portion of the cover member, such that the overlap portion overlaps a portion of the end portion of the cover member in a second direction that is perpendicular to the first direction.
