Electrophotographic photoreceptor, method of producing the same, process cartridge, and image-forming apparatus

An electrophotographic photoreceptor having a cylindrical support, a photosensitive layer and an outermost surface layer that are layered on or above the cylindrical support in this sequence;

• the outermost surface layer comprising a charge transport material and a curable resin;
• the charge transport material comprising a cross-linkable substance having a charge transport function;
• and
• the proportion of the content of the curable resin in the outermost surface layer increasing toward a surface, which is a far side from the photosensitive layer, of the outermost surface layer, the outermost surface layer being formed by ejecting an outermost surface layer coating liquid comprising at least the charge transport material and the curable resin by an inkjet method.
