Charging member

摘要

A charging member which is composed of a material containing a smaller amount of an ionic electrically conductive agent, and yet has a reduced resistivity and, when being energized, is less susceptible to an increase in electrical resistance, thereby assuredly preventing an imaging failure. The charging member comprises a base material and an ionic electrically conductive agent of a quaternary ammonium salt represented by the following general formula (1): <MATH> wherein R<1> to R<4> are alkyl groups, at least one of which is a C4-8 alkyl group and at least one of which is different from the at least one C4-8 alkyl group, X<n-> is an n-valent anion, and n is an integer of 1 to 6. <IMAGE>
