PURPOSE: To suppress the sag of coating liquid by increasing viscosity of the coating liquid and to uniformalize the film thickness over the entire part by adding a thickener to the charge transfer layer-forming liquid.

CONSTITUTION: The production of the photosensitive body by a dip coating method is executed by adding the thickener to the charge transfer layer forming liquid. The thickener is preferably added to an under coating layer-forming liquid and is not added to a charge generating layer-forming liquid. The examples of the thickener include an org. amide material, modified castor oil deriv., modified polyolefin wax material and org. clay deriv. The org. amide material is strong to a high-temp. treatment and the example thereof includes a fatty acid amide wax. The org. clay deriv. is formed by a composite cation compd. to smectite clay and the examples thereof include two kinds; amine- modified bentonite and amine-modified hectolite. The ratio at which the thickener occupies in the coating liquid is 2 to 20wt.%, more preferably 5 to 15wt.%.
