Abstract:
The present invention relates to an electrophotographic photoreceptor for positive charging, the photoreceptor comprising: a conductive support; and a single-layer type photosensitive layer disposed on the conductive support, the single-layer type photosensitive layer containing a binder resin, a compound (1) having hole transporting ability, and a compound (2) having electron-transporting ability, wherein the level Ah of a compound having a highest energy level of HOMO in the compound (1), the level BI of a compound having a lowest energy level of LUMO in the compound (2), and an energy level Ch of HOMO of another compound C which has a molecular weight of 500 or less and is contained in the photosensitive layer satisfy specific equations.

Claim (Index 5):
The electrophotographic photoreceptor according to  claim 1 , wherein the polyarylate resin has a structural unit represented by the following General Formula (1b): wherein Ar b1  to Ar b4  each independently represent an arylene group that may have a substituent, Z represents a single bond, an oxygen atom, a sulfur atom, or an alkylene group, m represents an integer of 0 to 2, and Y represents a single bond, an oxygen atom, a sulfur atom, or an alkylene group.
