Abstract
The present invention is directed to a polycarbonate resin comprising a structural unit represented by the following general formula (I), wherein the structural unit of general formula (I) occupies 5 to 100 mol % relative to all the structural units, and the limiting viscosity of the polycarbonate resin is 0.3 to 2.0 dl/g: wherein in the formula, R1 through R8 independently represent a hydrogen atom, a halogen group, an alkyl group having a carbon number of 1 through 9, an aryl group having a carbon number of 6 through 12, an alkenyl group having a carbon number of 2 through 5, an alkoxy group having a carbon number of 1 through 5, or an aralkyl group having a carbon number of 7 through 17.

A polycarbonate resin comprising a structural unit represented by the following general formula (I), wherein the structural unit of general formula (I) occupies 5 to 100 mol % relative to all the structural units, and a limiting viscosity of the polycarbonate resin is 0.3 to 2.0 dl/g:
- wherein in the formula, R1 through R8 independently represent a hydrogen atom, a halogen group, an alkyl group having a carbon number of 1 through 9, an aryl group having a carbon number of 6 through 12, an alkenyl group having a carbon number of 2 through 5, an alkoxy group having a carbon number of 1 through 5, or an aralkyl group having a carbon number of 7 through 17.
An electrophotographic photosensitive body comprising a photosensitive layer on a conductive substrate, wherein a polycarbonate resin having a structural unit represented by the following general formula (I) is used as a binder resin for the photosensitive layer:
- wherein in the formula, R1 through R8 represent a hydrogen atom, a halogen group, an alkyl group having a carbon number of 1 through 9, an aryl group having a carbon number of 6 through 12, an alkenyl group having a carbon number of 2 through 5, an alkoxy group having a carbon number of 1 through 5, or an aralkyl group having a carbon number of 7 through 17.
