PURPOSE:To couple an image carrier and turning force transmission member tightly with each other by arranging and forming needlelike grooves which serve as plural adhesive reservoirs in the fitting peripheral surface between the image carrier and its turning force transmission member. CONSTITUTION:The process cartridge 1, constituted by coupling the turning force transmission member 20 for rotating the image carrier 10 through an external driving force transmission member 30 with an end part of the image carrier 10 by fitting, has plural grooves 24 formed in the fitting peripheral surface between the turning force transmission member 20 and image carrier 10 as the needlelike adhesive reservoirs in the rotating direction. Consequently, the image carrier can be coupled tightly with the turning force transmission member with adhesives in the grooves in both the rotating direction and axial direction of the image carrier. |
