Abrégé
(EN)
An electrophotographic photoconductor including a conductive support, a charge generating layer, a hole transporting layer, and a hole transporting-protective layer, these layers being laminated in this order on the conductive support, wherein the hole transporting-protective layer contains a three-dimensionally crosslinked product which is obtained through chain polymerization of at least a radical polymerizable hole-transporting compound by irradiating the radical polymerizable hole-transporting compound with an active energy beam, and wherein the hole transporting-protective layer contains an oxazole compound represented by General Formula (1) or (2) below:

L'invention concerne un photoconducteur électrophotographique comprenant un support conducteur, une couche de production de charges, une couche de transport de trous et une couche de protection et de transport de trous, ces couches étant stratifiées dans cet ordre sur le support conducteur. La couche de protection et de transport de trous contient un produit réticulé tridimensionnellement qui est obtenu par polymérisation en chaîne d'au moins un composé radical polymérisable de transport de trous en éclairant le composé radical polymérisable de transport de trous par un faisceau d'énergie active. La couche de protection et de transport de trous contient un composé oxazole représenté par la formule générale (1) ou (2) ci-dessous.
