PURPOSE:To obtain the title body having an excellent electrifiable characteristics and durability without variance by incorporating a specific ratio of a thermoplastic acrylic component to the photosensitive layer comprising a carrier generating substance (CGM) and a binder resin on the weight basis of the CGM followed by dispersing the CGM uniformly in the title body. CONSTITUTION:The title body having the photosensitive layer contg. the CGM and the binder is prepared by coating a coating solution contg. 10-100pts.wt. the thermoplastic acrylic component on the basis of 100pts.wt. the CGM and dispersing the CGM in the coating solution into the prescribed photosensitive layer. The acrylic component preferably comprises a compd. shown by the formula wherein R and R' are each (unsatd.) satd. an alkyl, kan aralkyl, an aryl group or R may be H atom. The CGM preferably comprises an azo pigment having an electron attractive group. And also, the photosensitive layer may be a monolayer, but, is preferably a laminated layer. As the azo pigment disperses uniformly and stably for along period with protecting function of the binder contg. the acrylic component in the coating solution of forming theprescribed photosensitive layer, the title body obtd. by coating the coating solution has the excellent photosensitivity and the electron photographic characteristics. |
