Patent ID: 7813677

Claim:
A process cartridge detachably attachable to a main body of an image forming apparatus, the process cartridge comprising: a photosensitive member; a charging device configured to charge the photosensitive member, the charging device comprising: a conductive grid electrode that is configured in an angular U-shape as viewed from a cross section perpendicular to a longitudinal direction thereof, the grid electrode having a pair of opposing walls extending along the longitudinal direction; a frame holding the grid electrode by supporting each of the opposing walls of the grid electrode; and a charging wire attached to the frame and extended between the opposing walls of the grid electrode parallel to the opposing walls, wherein each of the opposing walls of the grid electrode is provided with a connecting portion having an extending portion that extends in the longitudinal direction and including either a protrusion or a notched portion, the frame is provided with a connected portion configured to engage with the connecting portion, and during assembling of the grid electrode to the frame, the grid electrode is slid in the frame relatively in the longitudinal direction, the extending portion provided in the connecting portion engages with the engaged portion, and the grid electrode and the frame are connected to each other; and a moving control member configured to control the grid electrode to restrict movement in a direction opposite to a direction that the grid electrode is slid in the frame when the grid electrode is mounted in the frame.
