Abstract
Official abstract text for this publication.
The photoconductor includes a conductive support, a photosensitive layer, and a protective layer. The protective layer is a polymer of a radical-polymerizable composition containing a perfluoropolyether compound including a radical-polymerizable functional group, a radical-polymerizable monomer including a radical-polymerizable functional group, and an inorganic fine particle including a radical-polymerizable functional group. The radical-polymerizable functional group of the perfluoropolyether compound is different from the radical-polymerizable functional group of the radical-polymerizable monomer and identical to the radical-polymerizable functional group of the inorganic fine particle.
First claim
Opening claim text (preview).
What is claimed is: 1. A photoconductor comprising a conductive support, a photosensitive layer disposed on the conductive support, and a protective layer disposed on the photosensitive layer, wherein the protective layer is a polymer of a radical-polymerizable composition comprising a perfluoropolyether compound including a radical-polymerizable functional group, a radical-polymerizable monomer including a radical-polymerizable functional group, and an inorganic fine particle including a radical-polymerizable functional group, and the radical-polymerizable functional group of the perfluoropolyether compound is different from the radical-polymerizable functional group of the radical-polymerizable monomer and identical to the radical-polymerizable functional group of the inorganic fine particle. 2. The photoconductor according to claim 1 , wherein the number of the radical-polymerizable functional groups of the perfluoropolyether compound is four or more. 3. The photoconductor according to claim 1 , wherein each of the radical-polymerizable functional groups is an acryloyl group or a methacryloyl group. 4. The photoconductor according to claim 1 , wherein the inorganic fine particle includes a metal oxide fine particle and an organic part including a radical-polymerizable functional group, the organic part being supported on the metal oxide fine particle and chemically bonding to the polymer. 5. A method for producing a photoconductor comprising a conductive support, a photosensitive layer disposed on the conductive support, and a protective layer disposed on the photosensitive layer, the method comprising: forming a coating film of a radical-polymerizable composition comprising a perfluoropolyether compound including a radical-polymerizable functional group, a radical-polymerizable monomer including a radical-polymerizable functional group, and an inorganic fine particle including a radical-polymerizable functional group on the photosensitive layer; and radical-polymerizing the radical-polymerizable functional groups in the coating film to form the protective layer on the photosensitive layer, wherein the radical-polymerizable functional group of the perfluoropolyether compound is different from the radical-polymerizable functional group of the radical-polymerizable monomer and identical to the radical-polymerizable functional group of the inorganic fine particle.
