Developing cartridge

摘要

A developing cartridge includes a case having a first sidewall and a second sidewall opposite to the first sidewall, and a developing roller disposed between the first sidewall and second sidewall. The developing roller can include a developing roller shaft and a developing roller member configured to carry a developing agent thereon, the developing roller member disposed around the developing roller shaft. Also, the developing cartridge can include 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 electrode can include, an extending portion extending in a direction away from the first sidewall. An outermost periphery of the driven coupling defines a projection plane projecting in a direction towards the electrode, wherein at least a part of the extending portion is disposed within the projection plane.

1. 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.
