To provide an electrophotographic photoreceptor of high sensitivity, high resolution and long life.

In the electrophotographic photoreceptor having a laminated photosensitive layer which is successively provided with at least an electric charge generating layer 1 and an electric charge transfer layer 2 on a conductive supporting body 3, the electric charge generating layer 1 is formed by applying a dispersed liquid which is obtained by dispersing at least a binder resin, an electric charge generating material and an organic solvent composed of at least one kind of ketone alcohol. In particular, an under coat layer 4 is formed between the conductive supporting body 3 and the electric charge generating layer 1 and the under coat layer 4 is preferably formed of a coating film which is insoluble in the ketone alcohol.
