Abstract: front page image
(EN)An electrophotographic photoconductor including: a conductive substrate; and at least a photoconductive layer on the conductive substrate, wherein an uppermost surface layer of the photoconductive layer includes a three-dimensionally crosslinked film formed through polymerization among compounds each containing a charge transporting compound and three or more [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups where the charge transporting compound has one or more aromatic rings and the [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups are bound to the aromatic rings of the charge transporting compound, wherein the polymerization starts after some of the [(tetrahydro-2H-pyran-2-yl)oxy]methyl groups have been partially cleaved and eliminated, and wherein the three-dimensionally crosslinked film has an ionization potential of 5.4 or higher.
(FR)La présente invention concerne un photoconducteur électrophotographique qui comprend : un substrat conducteur ; et au moins une couche photoconductrice sur le substrat conducteur, la couche de surface la plus haute de la couche photoconductrice comportant un film réticulé de façon tridimensionnelle qui est formé grâce à une polymérisation impliquant des composés qui contiennent chacun un composé de transport de charge et trois groupes [(tétrahydro-2H-pyranne-2-yl)oxy]méthyle ou plus. Le composé de transport de charge possède un ou plusieurs noyaux aromatiques, et les groupes [(tétrahydro-2H-pyranne-2-yl)oxy]méthyle sont liés aux noyaux aromatiques du composé de transport de charge. La polymérisation débute après que certains des groupes [(tétrahydro-2H-pyranne-2-yl)oxy]méthyle ont été partiellement clivés et éliminés, et le film réticulé de façon tridimensionnelle présente un potentiel d'ionisation de 5,4 ou plus.
