Abstract
The present invention provides a method of supporting and driving an electro-photographic photoreceptor in which total deflection can be improved and vibration sound due to the total deflection can be prevented, and an imaging apparatus realizing the method. A sliding bearing 3 fixed to a supporting member 2 consisting of a box member is fitted into an inner circumferential surface of an end portion of a cylindrical substrate 1 in the axial direction thereof. An annular driving member 4 is fitted into the other end portion of the cylindrical substrate 1 in the axial direction thereof. A threaded hole is provided at the central portion of the driving member 4. When a screw 5 is inserted into the threaded hole, the driving member 4 is deformed in an outer diametrical direction thereof and fixed to the inner circumferential surface of the cylindrical substrate 1. The driving member 4 is caused to be rotated by a driving source (not shown) which is connected to the driving member 4 via a gear 8. The cylindrical substrate 1 is interlocked with the rotation of the driving member 4 and is thereby rotated. Since the cylindrical substrate 1 is directly supported by the sliding bearing 3 and…
