    摘要： An electrophotographic apparatus includes an electrophotographic photosensitive member; a charger for charging the electrophotographic photosensitive member including a charging member supplied with a voltage and disposed in contact with the photosensitive member so as to form a nip with the photosensitive member to charge the photosensitive member; an exposure device; a developing device; and a transfer device. The photosensitive member includes a surface layer containing a charge-transporting material having an oxidation potential of 0.4-1.0 volt. Charging promoter particles are present at the nip between the photosensitive member and the charging member to injection-charge the photosensitive member. Because of the selection of the charge-transporting material and the presence of the charging promoter particles, the photosensitive member can be effectively injection-charged.

    摘要： An image-bearing member suitable for carrying an electrostatic image and/or a toner image is formed by forming a surface layer on a substrate or a photosensitive layer. The surface layer comprises a polymerized and cured product of a photoionically polymerizable compound having two or more functional groups, and shows excellent mechanical and electrical resistance as well as excellent charge-retaining characteristic. As a result, the surface layer provides an image-bearing surface suitable for electrophotography. The surface layer may be a protective layer or a photoconductive layer when it constitutes a photosensitive member.

    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.
