Patent ID: 8798492

Claim:
A developing cartridge for use with an image forming apparatus having a feeding member for supplying developing bias and a drive coupling, the 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 about a first axis line and a developing roller member configured to carry a developing agent thereon, the developing roller member disposed around the developing roller shaft; an electrode disposed on the first sidewall adjacent to the developing roller shaft, the electrode electrically connected to the developing roller member; and a driven coupling disposed on the second sidewall, the driven coupling configured to rotate about a second axis line, wherein the electrode includes a contact point configured to be contacted by the feeding member, the contact point being disposed within a plane of projection when the driven coupling is projected in a direction parallel to the second axis line towards the first sidewall.
