In optical printers and the like using this electrophotographic method, photosensitive drums having a photoconductive layer provided on the surface of a conductive metal cylinder are widely used. This photoreceptor drum is rotatably and removably arranged on the chassis of the optical printer, and around the photoreceptor drum there is a charger,
An exposure device, developing device, transfer device, and cleaning device are arranged. During printing, an electrostatic latent image is formed on the photoreceptor drum by exposing the photoconductive layer on the drum surface, this electrostatic latent image is developed with toner, and the formed toner image is transferred to recording paper. , then the surface of the photoreceptor drum is mechanically
Cleaning is done by electrical or magnetic means and the printing cycle described above is repeated.

It must be a high cylindrical body. Furthermore, the photoreceptor drum undergoes repeated printing cycles and is subjected to various stresses at this time.
It must have excellent mechanical strength and durability, and if there are problems with these characteristics, it becomes necessary to replace the photosensitive drum more frequently.
