The present invention relates to an electrophotosensitive material wherein a layer containing a binder resin and a pigment among a photosensitive layer is formed by applying and drying a coating solution prepared by dispersing the binder resin and the pigment in a dispersion medium containing alcohol represented by the formula (1): wherein R1, R2 and R3 are the same or different and represent a hydrogen atom or an alkyl group; the electrophotosensitive material is free from lowering of the sensitivity due to formation of agglomerates of the pigment and is superior in sensitivity characteristics.
An electrophotosensitive material comprising a photosensitive layer having at least a layer containing a binder resin and a pigment, wherein the layer is formed by dispersing a polyvinyl acetal as the binder resin and a phthalocyanine pigment as the pigment in an alcohol represented by the formula (1):
An electrophotosensitive material comprising a photosensitive layer having at least a layer containing a binder resin and a pigment, wherein the layer is formed by dispersing the binder resin and the pigment in an organic solvent, drying the dispersion to remove the organic solvent to prepare a powder in which the binder resin is adsorbed on the surface of pigment particles, and dispersing the powder in a dispersion medium to prepare a coating solution, and applying and drying the coating solution.
An electrophotosensitive material comprising a photosensitive layer having at least a layer containing a binder resin and a pigment, wherein the layer contains diacetone alcohol, characterized in that a sample collected from the layer has peaks at a detection time ranging from 5.3 to 7.5 minutes in gas chromatography at a thermal decomposition temperature higher than a boiling point of diacetone alcohol, and that the sample has peaks at the positions where a m/z value as a ratio of a mass to an electric charge is 43, 59 and 101, in a mass spectrum detected by a specific ion detection process of at least one peak of the gas chromatographic peaks.
A method of producing an electrophotosensitive material comprising a photosensitive layer having at least a layer containing a binder resin and a pigment, which comprises steps of:
