<P>PROBLEM TO BE SOLVED: To provide a process cartridge improved from conventional examples and capable of restricting displacement of a cleaning blade against an environment (temperature) fluctuation so as to enable a constantly stable cleaning performance, through optimally arranging a deformation absorption part. <P>SOLUTION: In a representative configuration of a process cartridge directed to this invention, the process cartridge comprises a blade 52a, blade support members 52b that support the blade 52a, and a cleaning frame body 51 having two securing portions 51d where the blade support members 52b are secured. In the cleaning frame body 51, at a process cartridge 2 detachably mounted to an image formation apparatus body and having wall faces facing the two securing portions 51d and an absorption wall face 51c that is continuous to the wall faces and absorbs deformation of the cleaning frame body 51, the absorption wall face 51c is in a concave shape protruded from a wall surface in a direction of a securing portion 51d. <P>COPYRIGHT: (C)2012,JPO&INPIT |
