Abstract
The present invention provides an image bearing member comprising an image bearing layer capable of bearing an image, a substrate for supporting the image bearing layer, and a weight portion arranged with the substrate asymmetrically with respect to a center of said substrate in a generatrix direction thereof.
Claims33
An image bearing member contacting with a charge member to which a vibrating voltage can be applied, comprising:
- an image bearing layer capable of bearing an image thereon;
- a base for supporting said image bearing layer;
- a drive force transmitting portion disposed at one end of said image bearing member in a generatrix direction thereof;
- and
- a weight portion provided to be contacted with substantially all of an inner peripheral surface of said base, said weight portion being arranged so that a center thereof is offset from a center of said base toward said drive force transmitting portion in the generatrix direction.
2 more elements
A process cartridge detachably mountable onto an image forming apparatus, comprising:
- an image bearing member having an image bearing layer capable of bearing an image thereon, a base for supporting said image bearing layer, and a drive force transmitting portion disposed at one end of said image bearing member in a generatrix direction thereof, and
- a charge member contacting with said image bearing member for charging said image bearing member, wherein a vibrating voltage is applied to said charging member;
- wherein said image bearing member has a weight portion disposed to be contacted with substantially all of an inner peripheral surface of said base, said weight portion being disposed so that a center thereof is shifted from a center of drive of said base toward said drive force transmitting portion in the generatrix direction.
An image forming apparatus, comprising:
- an image bearing member having an image bearing layer capable of bearing an image thereon, a base for supporting said image bearing layer, and a drive force transmitting portion disposed at one end of said image bearing member in a generatrix direction thereof;
- a charge member contacting said image bearing member for charging said image bearing member, a vibrating voltage being applicable to said charging member,
- wherein said image bearing member has a weight portion disposed to be contacted with substantially all of an inner peripheral surface of said base, said weight portion being disposed so that a center thereof is shifted from a center of drive of said base toward said drive force transmitting portion in the generatrix direction.
An image bearing member, comprising:
- an image bearing layer capable of bearing an image thereon;
- a base for supporting said image bearing layer;
- a conductive member contacted with an inner surface of said base and adapted to apply a predetermined potential thereto;
- and
- a weight portion arranged within said base,
- wherein said conductive member is abutted against an inner surface of said base under a force which is in the range of 10 to 200 g.
3 more elements
A process cartridge detachably mountable to an image forming apparatus, comprising:
- an image bearing member having an image bearing layer capable of bearing an image thereon, and a base for supporting said image bearing layer;
- and
- process means for performing an image forming process on said image bearing member;
- wherein said image bearing member has a conductive member contacted with an inner surface of said base to receive a predetermined potential therefrom when said cartridge is mounted onto a main body of said image forming apparatus, and a weight portion arranged within said base and wherein said conductive member is abutted against an inner surface of said base under a force which is in the range of 10 to 200 g.
1 more element
An image forming apparatus, comprising:
- an image bearing member having an image bearing layer capable of bearing an image thereon and a base for supporting said image bearing layer;
- and
- image forming means for forming an image on said image bearing member,
- wherein said image bearing member has a conductive member contacted with an inner surface of said base and adapted to apply a predetermined potential thereto, and a weight portion arranged within said base and wherein said conductive member is abutted against an inner surface of said base under a force which is in the range of 10 to 200 g.
