Abstract:
1. A developing cartridge, comprising: a case including a first sidewall and a second sidewall opposite to the first sidewall; a developing roller disposed between the first sidewall and the second sidewall, the developing roller including a developing roller shaft configured to rotate during development and a developing roller member configured to carry developing agent thereon, the developing roller member being provided around the developing roller shaft, the developing roller shaft configured to rotate about a first axis line during development; an electrode disposed at the first sidewall adjacent to the developing roller shaft, the electrode being electrically connected to the developing roller member; and a driven coupling disposed at the second sidewall, the driven coupling configured to be engaged with a drive coupling of an image forming apparatus and being configured to rotate about a second axis line during development, wherein the first axis line and the second axis line are disposed parallel to each other and spaced apart from each other, wherein the driven coupling is configured to be engaged with the drive coupling in a direction along the second axis line, and the electrode is disposed to contact a feeding member of the image forming apparatus within a plane of projection defined when the driven coupling is projected in a direction parallel to the second axis line towards the electrode.
