Abstract
A charging member, which electrically charges an object to be charged by being placed in contact with the object to be charged and by being applied with a voltage, is provided where the charging member includes an electroconductive base and brush bristles to come into contact with the object to be charged, and the brush bristles include at least one of etching fibers and divided fibers.
Claims26
A charging member, which electrically charges an object to be charged by being placed in contact with the object to be charged and by being applied with a voltage, said charging member comprising:
- an electroconductive base;
- and
- contact brush bristles that come into contact with the object to be charged, said contact brush bristles including at least one of etching fibers and divided fibers obtained from a conjugate fiber.
A process cartridge comprising:
- an electrophotographic photosensitive member;
- and
- at least one of a charging member provided in contact with said electrophotographic photosensitive member to electrically charge said electrophotographic photosensitive member, developing means, and cleaning means,
- wherein said charging member includes an electroconductive base and contact brush bristles that come in contact with said electrophotographic photosensitive member,
- wherein said contact brush bristles include at least one of etching fibers and divided fibers obtained from a conjugate fiber, and
- wherein said electrophotographic photosensitive member and said at least one of said charging member, said developing means, and said cleaning means are supported in one unit to be mountable to and demountable from an electrophotographic apparatus.
An electrophotographic apparatus comprising:
- an electrophotographic photosensitive member;
- a charging member provided in contact with said electrophotographic photosensitive member to electrically charge said electrophotographic photosensitive member;
- light exposure means;
- developing means;
- and
- image transfer means,
- wherein said charging member includes an electroconductive base and contact brush bristles to come into contact with said electrophotographic photosensitive member, said contact brush bristles including at least one of etching fibers and divided fibers obtained from a conjugate fiber.
