Abstract
A conductive composition containing at least zinc oxide whiskers. The conductive composition can be used to provide a conductive resing composition and a conductive coating composition, which have various uses, particularly in conductive layers, conductive supports or protective layers of electrophotographic photosensitive members.
Claims21
A conductive resin composition comprising conductive zinc oxide whiskers each having a tetrapod structure in an amount greater than or equal to 0.1 weight percent and a resin, said zinc oxide whiskers each being dispersed in the resin to form an electrical conducting path and said tetrapod structure comprises a central part and a needle crystal part, wherein a length from the base to the top of the needle crystal part is from 3 to 200 .mu.m and an aspect ratio of the needle crystal part is not less than 3.
