The present invention provides an electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, the photosensitive layer comprising a specific hole transferring material and/or electron transferring material and a binding resin of a polyester resin which is a substantially linear polymer obtained by using a specific dihydroxy compound represented by the general formula (1):

Electrophotosensitive material

The present invention provides an electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, the photosensitive layer comprising a specific hole transferring material and/or electron transferring material and a binding resin of a polyester resin which is a substantially linear polymer obtained by using a specific dihydroxy compound represented by the general formula (1): ##STR1## wherein R.sup.1 is an alkylene group having 2 to 4 carbon atoms; and R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an aryl group or an aralkyl group or the like. This photosensitive material is improved in sensitivity, and is also superior in adhesion to conductive substrate as well as mechanical strength such as wear resistance, etc.
