Abstract:
1. An image carrying cartridge comprising: a shaft defining an axial direction; an image carrying member carrying a developer image, the image carrying member being formed with a shaft insertion-hole extending in the axial direction through which the shaft is inserted and having one end and another end in the axial direction; a first casing comprising two first walls arranged in parallel to each other and having surfaces perpendicular to the axial direction of the shaft, one first wall opposing the one end of the image carrying member in the axial direction, another first wall opposing the other end of the image carrying member in the axial direction, each of the first walls being formed with a first through-hole; and a second casing comprising two second walls arranged in parallel to the two first walls, one second wall opposing the one first wall in the axial direction, another second wall opposing the other first wall in the axial direction, each of the second walls being formed with a second through-hole, the first casing and the second casing being coupled by insertion of the shaft through the first though-hole and the second through-hole to provide an inner space in which the image carrying member is accommodated; wherein the one second wall is interposed between the one end of image carrying member and the one first wall, the other second wall is interposed between the other end of the image carrying member and the other first wall, the one second wall comprising a guide portion provided on a surface opposite to the one end of the image carrying member of the one second wall, the guide portion being configured to guide the image carrying member at a position where the shaft insertion-hole is aligned with the second through-hole in the axial direction, when the image carrying member is disposed between the two second walls; and each of the second walls comprises a casing guide portion provided on a surface opposite to each of the first walls of each of the second walls, the casing guide portion being configured to guide the first casing at a position where the first through-holes are aligned with the second through-holes in the axial direction, when the second casing is coupled to the first casing.
