An electrophotographic photosensitive drum unit includes (a) a cylinder having a photosensitive layer at an outer periphery thereof, and (b) a drum flange provided at one end of the cylinder. The drum flange includes (i) a plurality of projections provided inside the drum flange and projected radially inwardly of the drum flange with a space between projections diametrically around the drum flange, and (ii) a recess provided at a position radially outside of an innermost portion of the projections.
摘要:
A method for dismounting a coupler from an electrophotographic photosensitive drum flange whose drum is usable with a cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus. The coupler receives a force rotating the drum from the main assembly when the cartridge is mounted and includes force receiving and spherical portions. The method includes the steps of inclining the coupler relative to a flange rotational axis, pushing a pin from one end to the other end thereof, both of which project from the spherical portion when the inclining step inclines the coupler, making part of the pin ride on a surface of a regulator inside the flange, and dismounting the coupler from the flange by applying a force to a free end of the coupler toward the part of the pin riding on the regulator surface.

A developing apparatus includes a developing container for containing a developer; a developer carrying member to be rotated while carrying the developer thereon, the developer carrying member being provided in an opening portion of the developer container; and a sealing member which extends in a circumferential direction of the developer carrying member in the vicinity of an end of the developer carrying member and regulates movement of the developer toward the end of the developer carrying member by a magnetic force, the sealing member including an arcuate portion extended along a peripheral surface of the developer carrying member and a non-arcuate portion disposed at an end, in the circumferential direction, of the arcuate portion. An end surface of the arcuate portion of the sealing member on a side where the non-arcuate portion is not provided, is inclined such that a phantom plane including the end surface is closer to the arcuate portion than a center of arcuation of the arcuate portion.

A developing device for developing an electrostatic latent image formed on an electrophotographic photoreceptor includes a hollow developing roller, a support member inserted in the hollow developing roller to support the developing roller, a flange member having a first engaging portion engaging with an outer surface of the support member and a second engaging portion engaging with an inner surface of the developing roller, and a gap-holding member disposed at one end of the developing roller, the gap-holding member having an abutment abutting against the electrophotographic photoreceptor for maintaining a gap between the developing roller and the electrophotographic photoreceptor. The abutment overlaps with the second engaging portion in the longitudinal direction of the developing roller.
摘要:
Conventionally, in the process for inspecting a molded product, a measurement point indicating a portion to be measured is defined by using attribution information, such as a tolerance difference, and a measurement program is created, or a manual measurement instrument is employed to conduct the measurement. According to the invention, provided is an information processing apparatus supporting general measurement operations, including those for manual measurements, by using attribution information, such as a dimension and a dimensional tolerance, that is added to a CAD model generated by a CAD apparatus.
摘要:
A developing apparatus, a process cartridge and an electrophotographic image forming apparatus which can obtain a good image, and an end portion regulating member provided in them. The end portion regulating members for regulating the layer thickness of developer passed through interstices between a developing blade for forming a layer of the developer having a predetermined thickness on the surface of a developing roller and magnetic seals provided on the longitudinally opposite end portions of the developing roller in opposed relationship with the surface of the developing roller is provided downstream of the developing blade with respect to the rotating direction of the developing roller.
