Document Type and Number:
WIPO Patent Application WO/2020/195290
Kind Code:
A1
Abstract:
A developing cartridge (1) includes: a casing (10); a developing roller (30); a first cam (61) positioned at one end portion (91) of the casing (10); a second cam (62) positioned at another end portion (92) of the casing (10); and a connection member (63) connecting the first cam (61) to the second cam (62). The first cam (61) is movable relative to the casing (10) and the developing roller (30) in a first direction between a first position and a second position. The second cam (62) is movable relative to the casing (10) and the developing roller (30) in the first direction between a third position and a fourth position. The second cam (62) moves from the third position to the fourth position due to a tensile force of the connection member (63) along with movement of the first cam (61) from the first position to the second position.
