ABSTRACT:
A photoconductor is disclosed, which comprises a conductive cylindrical support which is substantially not hollowed, the conductive cylindrical support having a drive transferring mechanism coaxially and unifiedly provided on at least one of the end portions thereof, the conductive cylindrical support having a photoconductive layer on the outer periphery. The moment of inertia I (g . cm.sup.2) of the substantially not-hollowed conductive support is in the range of 0.4.ltoreq.I.ltoreq.140 (g . cm.sub.2), the diameter thereof being in the range from 0.5 to 2.0 cm. When the relation of C/(S . .omega.).ltoreq.0.4 (where S (cm.sup.2) is the square measure of the portion of the photoconductive layer on the photoconductor; C (cal/.degree.C.) is the heat capacity of the substantially not-hollowed cylindrical support; and .omega. (rad/s) is the rotating speed in development) is satisfied, high quality images can be readily and stably obtained without damages of the drive system.
