Abstract:
A process unit includes a drum frame supporting a photoconductor drum and a development frame supporting a development roller. The development cartridge is swingably supported by the drum frame at a coupling joint provided at a first side of the development frame and a support portion provided at a second side of the development frame. A center of rotation of the development roller is located in a position shifted from a line segment connecting a center of rotation of the coupling joint and a center of rotation of the photoconductor drum to an upstream side with respect to a direction of rotation of the coupling joint as viewed in an axial direction of the development roller, such that the development roller is pressed against the photoconductor drum by the action of the rotatory force received by the coupling joint.

Claim (Index 1):
A process cartridge comprising:\n a photoconductor drum being rotatable about a first axis extending in a first direction; a development frame including a first side and a second side spaced away from the first side of the development frame in the first direction; a development roller being rotatable about a second axis extending in the first direction, the development roller being positioned between the first side of the development frame and the second side of the development frame in the first direction, the development roller including a roller shaft extending in the first direction; a coupling joint disposed at the first side of the development frame, the coupling joint being rotatable about a third axis extending in the first direction; and a first cylindrical part disposed at the first side of the development frame, the first cylindrical part being disposed at one end of the roller shaft in the first direction, wherein the development frame is swingable relative to the photoconductor drum about the third axis between a first position and a second position, wherein the first cylindrical part contacts an outer surface of the photoconductor drum in a state where the development frame is in the first position, and wherein the first cylindrical part is spaced apart from the outer surface of the photoconductor drum in a state where the development frame is in the second position.
