PURPOSE: To prevent the chipping in the part where a stopper roller comes into contact and to uniformize potential characteristics by providing a coated film having a nonuniform film thickness distribution on a cylindrical base body by using a coating method to cause the continuous flight of a coating compd. discharged from a very small aperture to a stripe shape while substantially averting the atomization of the coating compd.
CONSTITUTION: The coating film 14 having the nonuniform film thickness distribution is provided on the cylindrical base body 1 by using the coating method to cause the continuous flight of the electrodeposition coating compd. 4 discharged from the very small aperture 12 to the stripe shape while substantially averting the atomization of the coating compd. The nonuniform film thickness distribution having an arbitrary film thickness distribution in an arbitrary position is obtd. simply by changing the discharge rate of coating speed of the coating compd. and intermitting the discharge of the coating compd. as the method for causing the continuous flight of the coating compd. for forming the electrophotographic sensitive body discharged from the very small aperture 12 to the stripe shape while substantially averting the atomization thereof is used in such a manner. The state in which the coating compd. does not substantially atomize is obtd. by the continuous flight at ≤3°, more preferably 0° discharge angle to the stripe shape. The crack in the part where the stopper roller comes into contact is prevented in this way and the potential characteristics are uniformized.
