PRODUCTION OF ELECTROPHOTOGRAPHIC SENSITIVE BODY

PURPOSE:To provide the industrially advantageous process for producing the electrophotographic sensitive body which is so improved as to form good images. CONSTITUTION:A washing tank 30 which is provided with a driving means for vertically moving an aluminum cylindrical base body 4 while rotating this body without contact with the outside surface thereof in the upper part, is internally disposed with an integrated chip 32 connected to an ultrasonic oscillator 31, and in which a washing liquid is housed is used. The washing method which executes ultrasonic washing by vertically moving the aluminum cylindrical base body 4 so as to direct its side face to the integrated chip 32 in the washing tank by the above-mentioned driving means and rotating the aluminum cylindrical base body 4 at least during the one movement operation thereof is used as the washing method for the anodized film surface of the electrophotographic sensitive body in the process for producing this photosensitive body.
