The object of the present invention is to provide a positive charging electrophotographic photoreceptor having high sensitivity, low residual potential, and excellent chargeability, and relates to a positive charging electrophotographic photoreceptor including a conductive support, a photosensitive layer, and a protective layer in this order, the photosensitive layer containing a charge generation substance, a positive hole transport substance, and an electron transport substance in the same layer, in which the positive hole transport substance includes at least one of the compounds represented by any one of the following formulas (1) to (5), and a binder resin of the protective layer is an alcohol-soluble thermoplastic resin, providing that the symbols in the formula are defined in the specification.

##STR00001##

A method for producing an electrophotographic photoreceptor having a conductive substrate, and a photosensitive layer formed on the conductive substrate. The method includes the steps of preparing a coating liquid containing a charge generating material, and applying the coating liquid on to the conductive substrate, to thereby form the photosensitive layer. An absolute value of a zeta potential of the charge generating material is 5 mV or more, and a half-value width of a zeta potential distribution of the charge generating material is 100 mV or less.

Provided is an electrophotographic member in which the increase in tackiness is small even in an environment of high temperature and high humidity. The electrophotographic member includes an electroconductive substrate and a surface layer, the surface layer contains resin including at least one of a urethane bond and an amide bond, the resin includes a cationic structure and an anionic structure in a molecule, and also includes a particular main-chain structure with hydrophobicity.

Provided an electrophotographic member that contributes to the formation of a higher grade of an electrophotograph than ever for use in an ultralow-temperature environment.

The electrophotographic member has an electro-conductive resin layer, and the resin layer comprises a resin having a specific structure and an anion.
