Title:
DEVELOPING CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2020/195291
Kind Code:
A1
Abstract:
A developing cartridge 1 includes: a developing roller 30 rotatable about an axis extending in a first direction; a casing 10; and a first cam 61 provided at an outer surface of one end portion of the casing 10 in a second direction. The first cam 61 is movable in a third direction, relative to the casing 10 and the developing roller 30, between a first position and a second position closer to the developing roller 30 than the first position is to the developing roller 30 in the third direction. The first cam 61 has a first inclined surface 61a and a second inclined surface 61b. The first inclined surface 61a receives a pressing force F in the first direction directing from one end portion of the casing to another end portion of the casing in the first direction. A distance between the second inclined surface 61b and the casing 10 in the second direction varies as the second inclined surface 61b extends away from the developing roller 30 in the third direction. The first cam 61 is movable between the first position and the second position in response to application of the pressing force F to the first inclined surface 61a.
