CARTRIDGE AND DRUM UNIT FOR ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS: abstract simplified (18209546)

• This abstract for appeared for patent application number 18209546 Titled 'CARTRIDGE AND DRUM UNIT FOR ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS'

Simplified Explanation

The abstract describes a cartridge that contains a photosensitive drum and a developing roller, both of which can rotate. The cartridge is housed in a casing that has a groove on its outer surface. The groove is open to the outside and is defined by two side surfaces and a bottom surface. The rotational axis of the photosensitive drum and the groove are aligned along a line, with parts of the groove extending on either side of the line. The ends of the groove are open, creating a channel in the casing.

Original Abstract Submitted

A cartridge includes a photosensitive drum having a rotational axis about which the photosensitive drum is rotatable, a developing roller having a rotational axis about which the developing roller is rotatable, and a casing rotatably supporting the photosensitive drum and the developing roller. The casing includes a groove open to outside of the casing, with the groove being defined by a first side surface, a second side surface, and a bottom surface between the first side surface and the second side surface. As seen in the direction of the rotational axis of the photosensitive drum, the rotational axis of the photosensitive drum and the groove are positioned along a line in an extended direction, with at least a portion of a first projected part being positioned on one side of the line and at least a portion of a second projected part being positioned on the other side of the line. A first end of the groove and a second end of the groove are open such that the groove forms a channel in the casing along the extended direction.
