    • A graphite film excelling in heat conductivity, especially, a graphite film of high heat conductivity that even when its thickness is large, would not suffer damage by heat treatment. There is provided a process for producing a graphite film, including graphitizing a raw material film of a polymer film and/or carbonized polymer film, characterized by including (i) holding the raw film in a vessel capable of direct passage of current through voltage application and (ii) applying voltage to the vessel to thereby induce electrification so that graphitization is carried out. There is further provided a process for producing a graphite film, characterized by including the step of holding the raw material film in vessel (A) being electrifiable, subsequently holding the resultant vessel (A) in vessel (B) being electrifiable and effecting current passage through the whole so that graphitization is carried out.

    • A photosensitive material for electrophotography which comprises a conductive support, and a charge transport layer and a charge generation layer formed on the conductive support, is described. The charge generation layer is formed from a dispersion which is obtained by mixing X-type and/or .tau.-type metal-free phthalocyanine, with or without at least one other charge generation agent, and a resin binder in a solvent, which is capable of dissolving at least a part of X-type and/or .tau.-type metal-free phthalocyanine, to such an extent that a ratio between X-ray diffraction peak intensities at about 7.5.degree. and at about 9.1.degree. is in the range of 1:1 to 0.1:1. When the at least one other charge generation agent is used in combination, the charge generation layer is formed on the conductive support on which the charge transport layer is formed. If such other agent is not used, the charge generation layer is formed on the charge transport layer with a certain thickness. The photosensitive materials have good photosensitivity, image characteristics and printing resistance.
