Abstract
The present invention discloses a structure of supporting an image bearing member in which the tip portions of support pins inwardly projecting from side plates of a housing, come in contact with the bottoms of support-pin introducing holes in the image bearing member, so that tension applied to a grid electrode disposed opposite to the image bearing member is received by rigidity obtained by the image bearing member and the support pins. Predetermined gaps are formed between the side plates and the flange portions of the image bearing member.
Claims9
A structure of supporting the image bearing member of an image bearing unit in an image forming apparatus, in which said image bearing member is supported at opposite sides thereof by a pair of side plates formed at the housing of said image bearing unit and in which a grid electrode for a corona discharger is installed between said side plates, characterized in that:
- support pins as restrained from being axially moved, inwardly project from said side plates and are introduced into support-pin introducing holes formed in flange portions of said image bearing member at opposite sides thereof, so that said image bearing member is rotatably supported;
- and
- the tips of said support pins come in contact with the bottoms of said support-pin introducing holes with gaps formed between said side plates and said flange portions.
