摘要： A white electroconductive coating composition includes a white pigment having a whiteness of at least 60, a white conductive material having a whiteness of at least 50 and a volume resistivity of at most 1.times.10.sup.10 ohm.cm. The coating composition is suitable to provide a a coating film showing a whiteness of at least 60 and a surface resistivity of at most 1.times.10.sup.11 ohm/cm.sup.2. Such a white conductive layer may be formed on a back side of a surface insulating film of a transfer material carrying member of an electrophotographic image forming apparatus to provide a reference white pattern for detecting a density of a toner image formed on the carrying member, thereby allowing controlled image formation based on the detected density data.

摘要： A charging member is provided which can inhibit defective images due to poor charging and adhering substances from occurring even after being repeatedly used for a long time, and can inhibit deformation and defective images due to the C set, caused by a change in rotational speed accompanying such deformation even after being left standing in a stopping state for a long time. The charging member includes a conductive support and a surface layer. The surface layer includes a binder and resin particles dispersed in the binder, each resin particle having a depressed portion on its surface. Protrusions resulting from the resin particles are formed on the surface of the surface layer. The protrusions each have a depressed portion resulting from the depressed portion of the resin particle, and the surface of the resin particle is covered with the binder.

摘要： A charging member is provided having a support, a conductive elastic layer formed on the support and a surface layer formed on the conductive elastic layer. The surface layer contains a polysiloxane having at least one of structures represented by the following formulas (1a1), (1a2), (1b1) and (1b2): Toners and external additives used in the toners clinging to the charging member surface can be minimized even through repeated use over a long period of time, thus the charging member can perform stable charging and image reproduction even when used in the DC contact charging method.
