PURPOSE: To provide the process for production of the aluminum pipe for the electrophotographic photoreceptor with which a good ground surface is obtainable and productivity is good by removing the burrs of an aluminum metal generated heretofore by machining.
CONSTITUTION: This process for production of the aluminum pipe for the electrophotographic photoreceptor comprises axially feeding the aluminum pipe 3 of ≤10μm surface roughness finished to a prescribed size and shape by drawing after hot extruding between a rotating grinding wheel 1 and a feed roller 2 rotating in the same direction as the rotating direction of this rotating grinding wheel 1 to form grooves in a circumferential direction, subjecting the aluminum pipe to surface grinding not to impart regularly to the twill shapes of the rugged parts of the grooves and inter-groove intervals to finish the pipe to a ≤5.0μm Rz surface roughness range, and further, subjecting the aluminum pipe to rolling by many pieces of roller burnishing devices to roll only the projecting parts among the twill shapes of the rugged parts consisting of the irregular grooves subjected to the grinding treatment, thereby subjecting the pipe to a surface treatment to ≤1.0, more preferably 0.2 to 0.8μm Rz surface roughness.
