Abstract: The present invention provides an electrophotosensitive material containing the diamine derivative represented by the following general formula (I) and at least one selected from the group consisting of the hydrazone compound, fluorene compound and m-phenylenediamine compound. ##STR1## wherein R.sup.5 to R.sup.9, l, m, n, o and p are as defined.

Abstract: Disclosed is an electrophotographic photosensitive material containing in a photosensitive layer an m-phenylenediamine compound represented by the following general formula [I]: ##STR1## wherein R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are groups substituted at meta-positions to the nitrogen atoms and represent a hydrogen atom, an alkyl group, an alkoxyl group or a halogen atom, with the proviso that at least two of R.sup.5, R.sup.6, R.sup.7 and R.sup.8 represent an alkyl group, alkoxyl group or a halogen atom, and R represents a hydrogen atom, an alkyl group, an alkoxyl group or a halogen atom.This meta-substituted m-phenylenediamine compound of general formula [I] is hardly crystallized in a resin but is sufficiently dissolved in the resin, and therefore, the concentration of the compound in the resin can be increased and the mobility can be enhanced. Accordingly, an electrophotographic photosensitive material having an increased sensitivity can be provided.

Abstract: 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.

Abstract: A photoconductive material for use in electrophotography comprising a rhodanine derivative and a halogen-containing polymer. The marked feature of the invention is to use a compound of the following formula ##STR1## wherein X represents ##STR2## and R represents a substituent such as an alkyl, aryl or amino group.
