ABSTRACT:
An object of the invention is to provide a photoreceptor drum exceedingly advantageous for obtaining clear images free from positional image shifting and image blurring. In the invention, a photoreceptor drum is constituted of a drum main body and a first and second flange members to be attached respectively to both lengthwise-direction ends of the drum main body. The drum main body is constituted of a cylindrical body and a photosensitive layer formed on the surface of the cylindrical body, and the cylindrical body has a fitting hole formed in each end thereof. The first and second flange members have cylindrical parts to be fitted into and fixed to the fitting holes in the drum main body, and further have shaft support parts. The photoreceptor drum has been formed so that the radial deflection thereof based on a central axis L connecting the centers of the shaft support parts of the first and second flange members is 15 μm or less.
