    摘要： An electrophotographic photosensitive drum usable with an electrophotographic image forming apparatus, includes a non-circular twisted projection (72a) having a cross-section with a plurality of corner portions, the non-circular twisted projection being provided at one longitudinal end of the electrophotographic photosensitive drum and being engageable with a non-circular twisted hole (73a) having a section with a plurality of corner portions, the non-circular twisted hole being disposed at a central portion of a driving rotatable member (73) of a main assembly of the image forming apparatus; and a second electroconductive member (71) contactable with a first electroconductive member (70) electrically connected with a main assembly of the image forming apparatus, the first electroconductive member being disposed in the hole to provide a grounding of the electrophotographic photosensitive drum, the second electroconductive member being provided on the projection and being electrically connected with the electrophotographic photosensitive drum. A contact position (b2) between the second electroconductive member and the first electroconductive member moves in interrelation with the projection being retracted toward the hole by rotation of the driving rotatable member when the twisted projection is engaged with the hole and rotates integrally with the projection when in use for driving the drum.

    摘要： The present invention provides magnetic members (23) forming magnetic seals (21) at the ends of a developing sleeve (5) with gaps (g) between the sleeve and the seals. As a bias voltage is applied to the sleeve and the same voltage is applied to the magnetic seals through the support (7a) of a doctor blade (7), the surface potentials in the vicinity of the seals are made equal to prevent both leak out and accumulation of developer particles.

    摘要： A magnetic seal mounting method for mounting a magnetic seal member to a developing frame which has a magnetic seal mounting portion extended in a direction crossing with a longitudinal direction of a developing roller mounting portion for mounting a developing roller at each of one and the other longitudinal ends of the developing roller mounting portion, and a supporting member mounting portion for mounting a supporting member for supporting a developing blade extended along the longitudinal direction of the developing roller mounting portion, the method comprising the steps of: (a) engaging the magnetic seal member to the magnetic seal mounting portion while an elastic member between the magnetic seal mounting portion and the magnetic seal member is deformed, when the magnetic seal member is mounted to the magnetic seal mounting portion; (b) mounting the supporting member to a developing frame so that position of the magnetic seal member is regulated by the supporting member for supporting the developing blade to prevent disengagement of the magnetic seal member mounted to the magnetic seal mounting portion therefrom, thus mounting the developing blade; and (c) mounting the developing roller to the developing roller mounting portion provided in an including while flexing the developing blade after the developing blade is mounted to the developing frame.
