PURPOSE:To obtain an image superior in contrast by using a specified combination of the triboelectrification characteristics of a fixing resin medium and the semiconductor characteristics of a photoconductive material. CONSTITUTION:The photoconductive toner is formed by dissolving or dispersing the photoconductive material as an essential component into the fixing resin medium, and when the photoconductive material is a p-type semiconductor, it is combined with the fixing resin positive in triboelectrification characteristics, and when it is an n-type semiconductor, it is combined with the negative fixing resin. The resin is combined with the photoconductive material in an amount of 0.2-10, preferably, 0.3-5pts.wt. of the photoconductive material. It is preferred to use the granulated toner, when needed, in the form classified into a particle diameter of 9-12mum. |
