    摘要： An electrophotographic photosensitive member is formed by disposing a photosensitive layer and a protective layer in this order on an electroconductive support. The protective layer is formed from a resin obtained by polymerization of a curable acrylic monomer having at least three acrylic groups, i.e., acryloyl and/or methacryloyl groups. The protective layer not only shows a good durability against wearing but also can contain fine electroconductive particles therein with a good dispersibility because of the presence of the acrylic groups aiding the dispersion.

    摘要： An image holding member rich in durability and suitably used as an electrophotographic photosensitive member or an electrostatic image-holding dielectric member is prepared by coating a support with a resinous layer formed by polymerization of a phosphazene polyene represented by the following formida: ##STR1## wherein R.sub.1 denotes an ethylenically unsaturated group, preferably an acrylic group represented by --R.sub.2 --OCO--C(R.sub.3)=CH.sub.2, wherein R.sub.2 denotes an alkylene group, arylene group, alkyl-substituted arylene group, alkylamide group or arylamide group, and R.sub.3 denotes a hydrogen atom or a methyl group. The resinous layer may constitute a photosensitive layer, a dielectric layer, or a protective layer covering these layers.
