CYLINDRICAL ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PURPOSE: To provide an electrophotographic photoreceptor which generates little vibration for contact electrification process or in contact with a cleaning blade. CONSTITUTION: This electrophotographic photoreceptor is obtd. by filling a cylindrical supporting body comprising an aluminum hollow pipe having <=1.5mm thickness with a resin filler having 1.0×10<-5> to 5.0×10<-5> cm/ deg.C coefft. of linear expansion. The resonance energy is absorbed so that the photoreceptor generates little vibration. Further, secondary faults which affects the dimensional accuracy of the photoreceptor drum can be avoided by thermal expansion and contraction of the filling material.
