摘要:
A process cartridge detachably mountable to a main assembly of an image forming apparatus, the cartridge comprising a photosensitive member, a developing means for developing a latent image formed on the photosensitive member, a first frame containing the developing means; and a second frame coupled with the first frame, the second frame including a developer containing portion for containing a developer to be supplied to the developing means to develop the latent image, wherein the second frame is a selected one of plural secondary frames engageable with the first frame and having different developer containing capacities.
摘要:
The present invention provides a process cartridge mountable to an image forming apparatus, comprising a rotary member, a holding member for holding the rotary member, and a plurality of rolling members assembled between the rotary member and the holding member independently from the holding member.
摘要:
The present invention provides a process cartridge mountable to an image forming apparatus, comprising a frame, an image bearing member, process means acting on the image bearing member, and a gripper for gripping the process cartridge. The gripper portion is provided on said frame at a position offset from a longitudinal center of the process cartridge toward a position where the frame is subjected to a greater mounting resistance generated by engagement between the process cartridge and a member on the main body, when the process cartridge is mounted to the image forming apparatus.
摘要:
A frame for a process cartridge, which is detachably mountable to an electrophotographic image forming apparatus and which comprises an electrophotographic photosensitive member and a process device or devices actable on the electrophotographic photosensitive member. The frame includes a base member having a mounting portion for mounting the process device or devices and an elastic sealing member for preventing leakage of a developer from the process cartridge when the process cartridge is assembled, wherein the base member and the elastic sealing member are integrally molded.

A steering wheel having a `T` type spoke is attached to a steering column, with an axis of symmetry of steering wheel being angularly biased through an angle y relative to the forward direction of a vehicle, with the direction of the vehicle being stabilized on a stage of a toe-in tester. The vehicle is placed on the stage with the front wheels of the vehicle mounted on drive rollers, and the drive rollers are moved in a manner to place the axes of the drive rollers perpendicular to the axis of the stage as well as to the planes of rotation of the front wheels. Thereby, slide-slipping angles .alpha..sub.R, .alpha..sub.L and camber angles C.sub.NR, C.sub.NL of the right and left front wheels respectively, are determined so as to determine the compensating angle y, according to the equationy=a(.alpha..sub.R +.alpha..sub.L)+b(C.sub.NR -C.sub.NL)+c,wherein a,b,c represent constants determined by the type of vehicle involved.
摘要:
A two-layered copper-clad laminate material in which a copper layer having a thickness of 1 to 5 μm is formed by means of sputtering or electroplating on one surface or both surfaces of a polyimide film having a thickness of 12.5 to 50 μm after a plasma treatment is performed in a nitrogen gas atmosphere, the two-layered copper-clad laminate material being characterized in that the dissolution of the aforementioned polyimide film with an etching liquid is delayed compared with a polyimide film that is not subjected to the plasma treatment, the aforementioned dissolution being delayed as a consequence of modifying the surface of the polyimide film by incorporating nitrogen into the polyimide film by means of the plasma treatment in the nitrogen gas atmosphere.
