Disclosed is an organic photoconductive material for the electrophotography, which comprises a linear high-molecular-weight polymer having a rhodanine derivative of the following formula incorporated as a substituent: ##STR1## In this derivative group, a benzylidene group or the like is bonded to the 5-position of the rhodanine ring. A photosensitive material comprising a polymer having this rhodanine derivative group shows a photoconductivity to visible rays even without addition of a charge-generating pigment.
