<P>PROBLEM TO BE SOLVED: To provide a photoreceptor adjusted to desired sensitivity without spoiling potential stability in the case of repetitive use, and an image forming method using the photoreceptor. <P>SOLUTION: The electrophotographic photoreceptor is constituted by laminating a charge generating layer incorporating at least charge generating substance and pigment and a charge transporting layer incorporating charge transporting substance on a conductive base substance in this order. In the photoreceptor, assuming that Ip (ionized potential) of the charge generating substance is Ip(CGM), the Ip of the pigment is Ip(PIG) and the Ip of the charge transporting substance is Ip(CTM), they satisfy 0.05<|Ip(CGM)-Ip(PIG)|<0.5 and 0<|Ip(CGM)-Ip(CTM)|<0.5. <P>COPYRIGHT: (C)2004,JPO |
