ABSTRACT:
An electrophotographic photoconductor in which generation of a ghost phenomenon caused by exposure is avoided and potential change before and after continuous printings is insignificant. A functionally separated type electrophotographic photoconductor includes at least a charge generation layer containing a charge generation agent and a charge transport layer containing a charge transport agent, the two layers being sequentially laminated on a conductive substrate. A ratio of the maximum intensity of a halo pattern to a peak intensity of a maximum diffraction peak is less than 0.3 in an X-ray diffraction pattern obtained by a powder method using Cu Kα line of a test coating film produced from a test coating liquid that is prepared by adding the charge transport agent into a coating liquid for the charge generation layer in an equal mass of the charge transport agent to a mass of the charge generation agent.
