Claims

[Scope of utility model registration request]

(1) In a supporting device for a photosensitive drum of an electrostatic copying machine, in which an electrostatic latent image formed on a photosensitive drum in an exposure area is made visible by a developing device, both ends of the photosensitive drum are Abuts on the outer peripheral surface at at least three points,
A plurality of support members are provided to allow rotation of the photosensitive drum and support it, and two sets of support members forming a pair among the support members are:
The remaining at least one pair of supporting members is arranged with the exposure area and the developing device interposed therebetween, and the remaining at least one pair of supporting members is arranged on the side away from the two sets of supporting members. A support device for a photosensitive drum of an electrostatic copying machine, characterized in that the photosensitive drum is elastically biased.

(2) One of the remaining at least one pair of supporting members is a rotating body that receives power from a driving means to rotationally drive the photosensitive drum. A support device for a photosensitive drum of an electrostatic copying machine according to item 1. - (3) A gear integrally formed on the outer peripheral surface of the photosensitive drum at one end of the photosensitive drum meshes with a gear coaxially provided on one of the remaining at least one pair of supporting members. A support for a photosensitive drum of an electrostatic copying machine according to claim 1, wherein the one support member receives power from a driving means to rotate the photosensitive drum. Device.
