Electrophotographic sensitive body and image forming method
专利汇可以提供Electrophotographic sensitive body and image forming method专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve the electrifiability and the photosensitivity of the subject body, and to stabilize the potential of the exposed and the nonexposed parts of the body at the time of copying large volumes of sheets, and to uniformize the image density of the body by incorporating a specified ketone compd. in the sensitive body. CONSTITUTION:In the sensitive body obtd. by laminating a charge generating layer 1 and a charge transfer layer 2 in this order on a supporting body 3, the layer 1 is formed by dispersing a charge generating pigmenet (a) having positive hole transferring property and the ketone compd. (b) shown by formula I in a binding resin. The component (a) is preferably composed of a phthalocyanine type pigment (such as a X type metal free phthalocyanine), a squarylium type or a perylene type pigment. The component (b) is incorporated in the component (a) in an amount of 0.01-2 equivalents on the basis of the component (a), and is preferably composed of a compd. shown by formula II. In the formula, A is an aromatic or a heterocyclic ring group, X is hydrogen or halogen atom, R1 is hydrogen atom or alkyl group, etc., R2-R6 are each hydrogen atom or alkyl group, etc., (n) is 0 or 1, (m) is 1 or 2.，下面是Electrophotographic sensitive body and image forming method专利的具体信息内容。
