PURPOSE:To improve image performance and to enhance the light transmittance of a base and conductive layer by constituting the base of a seamless belt consisting of a biaxially stretched thermoplastic polyester resin and an over coat layer formed on the outside of the belt. CONSTITUTION:The base is constituted of the seamless belt consisting of the biaxially stretched thermoplastic polyester resin and the over coat layer formed on the outer side of the belt. The polyester resin to be used is exemplified by polyethylene terephthalate, polybutene terephthalate, etc. A cylindrical film formed of a polyester resin is used as the seamless belt. A resin which has excellent film formability and has the good adhesiveness to the seamless belt is selected as the resin constituting the over coat layer. Image defects are thereby eliminated and the high ray transmittance to allow exposing even from the rear surface of the photosensitive body is obtd. |
