PURPOSE:To obtain a photoconductive toner high in photosensitivity and superior in fixability by dispersing cores composed essentially of a material generating an electrostatic charge on absorption of light into a matrix composed essentially of charge transfer material in the form of plural domains. CONSTITUTION:The matrix 1 is composed essentially of a material mainly contg. the charge transfer material, and this matrix 1 has both functions of transfer of charge generated by the matrix on light absorption and fixing of the toner. The plural cores 2 made of charge generating material on light absorption are dispersed in the form of domains into the matrix, thus permitting the photoconductive toner to be prevented from deterioration of light utilization efficiency in spite of small sizes of individual cores, and light to be transmitted down to the lower part of the toner by control of the number of the cores, accordingly, charge to be generated from the upper layer to the lower layer by absorption of the light, and hence, photosensitivity to be fully enhanced. |
