Abstract:
A method for manufacturing a porous cylindrical photoreceptor drum comprising the steps of:forming a cylindrical photoreceptor drum byforming a transparent conductive layer on a transparent cylindrical support member, andforming a heterogenous multilayer conductive particle receiving layer on the transparent conductive layer;rotating the cylindrical photoreceptor drum around an axis along a centerline of the drum;placing a moving mask pattern having pre-determined holes in momentary intimate contact with a circumferential contact surface of the rotating cylindrical photoreceptor drum, wherein the instantaneous relative velocity between the moving mask pattern and the rotating cylindrical photoreceptor drum is zero along the circumferential contact surface; andforming pores in the heterogenous multilayer conductive particle receiving layer by jet-blasting minute particles through the pre-determined holes in the moving mask pattern along the circumferential contact surface and into the rotating heterogenous multilayer conductive particle receiving layer.
