A top surface layer of an electrophotographic photosensitive element (e.g., a charge-transporting layer) is rendered to contain a cyclic polysilane represented by the following formula (1). (see formula 1) In the formula, R1 and R2 are the same or different from each other and each represents a group such as an alkyl group, an aryl group, and "m" denotes an integer of not less than 4. The cyclic polysilane may be a copolysilane. The content of the cyclic polysilane may be about 0.01 to 10% by weight relative to the whole components of the top surface layer.
L'invention concerne un photorécepteur électrophotographique dont la couche la plus à l'extérieur (telle qu'une couche de transport de support) contient un polysilane cyclique représenté par la formule générale (1), dans laquelle R?1¿ et R?2¿ sont chacun indépendamment alkyle, aryle ou analogue, et m est un nombre entier supérieur ou égal à 4. Le polysilane cyclique peut être un copolysilane et la proportion de ce polysilane cyclique est comprise entre 0,01 et 10% en poids sur la base de la totalité du composant constituant de la couche la plus à l'extérieur.
