An image support apparatus including a pair of rotatable disk shaped members, a cylindrical member supported and fixed at both ends by the pair of disk shaped members, a flexible image supporter shaped like a thin cylinder and formed with a photosensitive layer at the outer peripheral surface, support members being disposed on an outer peripheral surface of the cylindrical member for supporting the image supporter, a charge roller abutting the outer peripheral surface of the image supporter for uniformly charging the outer peripheral surface, and a frame. A distance between a portion of the image supporter supported by the support member and an end of the charge roller is set to a length to prevent the image supporter, which is bent as the charge roller abuts the image supporter, from becoming permanently deformed.

An image carrier device which includes a flexible cylindrical thin image carrier, a support member for supporting both ends of the image carrier and a cylindrical member having an outer diameter smaller than an inner diameter of the image carrier. The cylindrical member is disposed inside of the image carrier, wherein the cylindrical member is disposed at an interval between an outer peripheral surface of the cylindrical member and an inner peripheral surface of the image carrier, such that the interval is smaller than the allowable deformation of the image carrier.
