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 K.alpha. 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.
