A method of forming an electrophotographic photoreceptor capable of
forming a smooth coating film free of pinholes, bubbles, surface
unevenness, etc. in a short time as a coating film for forming a
photosensitive layer is provided. The method includes heating and drying
a coating film formed by coating a coating solution containing
ingredients of the photosensitive layer and a solvent medium containing
30% by weight or more of a solvent having a relative evaporation rate of
less than 1.7 represented by the following formula (1) in an air stream
at a temperature of 50.degree. C. or higher and 130.degree. C. or lower
supplied from a blowing nozzle, by a far infrared ray heating method and
an induction heating method, by using, for example, a drying apparatus,
thereby manufacturing the electrophotographic photoreceptor: (relative
evaporation rate)=(time for evaporating n-butyl acetate)/(time for
evaporating solvent) (1).
