An electrophotographic photoreceptor including an electroconductive substrate; a charge generation layer located overlying the electroconductive substrate; a charge transport layer located overlying the charge generation layer; and an outermost layer located overlying the charge transport layer. The charge transport layer includes a positive hole transport material having the following formula (1): n n n n n n n n n n wherein each of R1 to R26 independently represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an alkoxyl group having 1 to 4 carbon atoms, and a compound having the following formula (2): n n n n n n n n n n n n wherein each of R27 and R28 independently represents a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group. |
