Abstract

PURPOSE:To obtain an electrophotographic photoconductive toner high in photosensitivity and free from service life deterioration environmental pollution problem etc., by allowing a nontoxic oxide semiconductor to adsorb 2 kinds or more of specified dyes. CONSTITUTION:2 Kinds or more of n-type dyes and p-type dyes are used in combination for adsorption to an n-type semiconductor, such as ZnO or TiO2 oxide semiconductor. For example, fluorescein (p-type) and crystal violet (n-type) or malachite green (n-type) are selected to combine (p-type and n-type) or (n-type and p-type), and this combination is adsorbed to the above oxide semiconductor to form a toner.
