Abstract:
A polyarylate resin is represented by general formula (1) shown below. In general formula (1), R 1  represents a hydrogen atom or methyl group. R 2  and R 3  each represent a hydrogen atom or an alkyl group having a carbon number of at least 1 and no greater than 4. R 2  and R 3  are not the same as one another. When R 1  represents a hydrogen atom, R 2  and R 3  are not bonded to one another. When R 1  represents a methyl group, R 2  and R 3  are optionally bonded to one another to form a ring. r and s each represent a number greater than or equal to 0 and less than or equal to 49. t and u each represent a number greater than or equal to 1 and less than or equal to 50. r+s+t+u=100. r+t=s+u.

Claim (Index 7):
An electrophotographic photosensitive member comprising:\n a conductive substrate; and a photosensitive layer, wherein the photosensitive layer contains a charge generating material, a hole transport material, and a binder resin, and the binder resin includes the polyarylate resin according to  claim 1 .
