Abstract
An image forming apparatus having a detachable imaging cartridge which includes a photosensitive member charged by a charge brush having brush fibers. At least one of the photosensitive member and the charging brush is detachable from the imaging cartridge, and the detachable one is attached to the imaging cartridge through a guide member so that the brush fibers of the charge brush are indented toward a downstream side relative to a predetermined position of the charge brush with respect to the rotational direction of the photosensitive member.
Claims22
An image forming apparatus comprising:
- an image bearing member;
- a charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith;
- a holder for rotatably holding said image bearing member and for holding said charge brush in contact with said image bearing member, said holder detachably holding at least one of said image bearing member and said charge brush;
- and
- guide means for relatively guiding said detachable one into said holder from a predetermined direction so that said fibers of said charge brush are inclined along the rotational direction of said image bearing member.
An image forming apparatus comprising:
- an image bearing member;
- a charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith;
- a holder for rotatably and detachably holding said image bearing member and for holding said charge brush in contact with said image bearing member;
- and
- guide means for guiding said image bearing member into said holder from an upstream side of said charge brush with respect to the rotational direction of said image bearing member.
An image forming apparatus comprising:
- an image bearing member;
- a charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith;
- a holder for rotatably holding said image bearing member and for detachably holding said charge brush in contact with said image bearing member;
- and
- guide means for guiding said charge brush into said holder from an opposite direction with respect to the rotational direction of said image bearing member.
An imaging cartridge detachably provided in an image forming apparatus comprising:
- an image bearing member being held rotatably and detachably in said imaging cartridge;
- a charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith, said charge brush being fixedly held in said imaging cartridge;
- and
- guide means provided on the inner surface of a side wall of said imaging cartridge for guiding said image bearing member into said imaging cartridge from an upstream side of said charge brush with respect to the rotational direction of said image bearing member.
An imaging cartridge detachably provided in an image forming apparatus comprising:
- an image bearing member being rotatably held in said imaging cartridge;
- a charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith, said charge brush being detachably held in said imaging cartridge;
- and
- guide means for guiding said charge brush into said imaging cartridge from an opposite direction with respect to the rotational direction of said image bearing member.
In an image forming apparatus which includes a rotatable and detachable image bearing member and a charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith, a method for attaching the image bearing member to a frame provided in said image forming apparatus comprising the following steps of:
- fixedly providing the charge brush in said frame;
- and
- inserting said image bearing member into said frame from an upstream side of said charge brush with respect to the rotational direction of said image bearing member.
In an image forming apparatus which includes a rotatable image bearing member and a detachable charge brush having brush fibers for charging the surface of said image bearing member by contacting the fibers therewith, a method for attaching the charge brush to a frame provided in said image forming apparatus comprising the following steps of:
- fixedly providing the image bearing member in said frame;
- and
- inserting said charge brush into said frame from an opposite direction with respect to the rotational direction of said image bearing member.
