Method for producing electrophotographic photoreceptor having sublimable antioxidant in coating liquid
Abstract:
An method for producing an electrophotographic proreceptor includes a first coating step of applying a coating liquid containing a sublimable antioxidant and a photoconductive substance, onto a conductive substrate to form a first coating film thereon, a first drying step of drying the formed first coating film by heating to form a first photosensitive layer, a second coating step of applying the coating liquid used in the first coating step, onto the first photosensitive layer to form a second coating film, and a second drying step of drying the formed second coating film by heating to form a second photosensitive layer. In the second drying step, the drying condition is made to differ from the drying condition in the first drying step so that a degree of sublimation of the antioxidant in the second drying step is lower than that of sublimation of the antioxidant in the first drying step.
