Abstract

L'invention concerne un matériau photosensible d'électrophotographie constitué d'un substrat électroconducteur, d'une couche intermédiaire formée sur le substrat et d'une couche supérieure formée sur la couche intermédiaire. La couche intermédiaire est constituée de A un photoconducteur polymère organique et B un composé nitro aromatique polycyclique accepteur électrons dans un rapport pondéral A/B compris entre 6/1 et 1/6, et la couche supérieure est constituée C d'une phtalocyanique ou d'un dérivé de phtalocyanine et B du dit composé nitro aromatique polycyclique, incorporés dans un liant, dans un rapport pondéral C/B compris entre 10/5 et 10/25.Provided is an electrophotography photosensitive material consisting of an electroconductive substrate, an intermediate layer formed on the substrate, and a top layer formed on the intermediate layer. The intermediate layer consists of A an organic polymer photoconductor and B an electron-accepting polycyclic nitro aromatic compound in an A / B weight ratio between 6/1 and 1/6, and the upper layer consists of C of a phthalocyanic or d 'a derivative of phthalocyanine and B of said polycyclic aromatic nitro compound, incorporated in a binder, in a C / B weight ratio of between 10/5 and 10/25.
