White electroconductive coating composition and transfer material-carrying member |
摘要 |
<p>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 1x10<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 1x10<11> ohm/cm<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. <IMAGE></p> |
