Abstract: A cleaning member for an image forming apparatus, includes a core, a foamed elastic layer disposed by winding a strip-shaped foamed elastic member on an outer peripheral surface of the core in a helical form so as to extend from one end of the core to the other end, and a bonding layer for bonding the core and the foamed elastic layer together, wherein the area of a region within a surface at one or both ends at least in a longitudinal direction of the foamed elastic layer on a side facing the outer peripheral surface of the core, contacting the outer peripheral surface of the core via the bonding layer is substantially 35% or more by area ratio per unit area.

Abstract: An image forming apparatus includes an electrophotographic photoconductor that includes an outermost surface layer containing a binder resin having a structural unit represented by general formula (A) below and a charge transporting material having a butadiene trimer structure in a single molecule, a charging unit that charges the electrophotographic photoconductor, an electrostatic latent image forming unit that forms an electrostatic latent image, a toner image forming unit that forms a toner image, and a transfer unit that transfers the toner image formed on the electrophotographic photoconductor onto a transfer-receiving body, where R11 and R12 each independently represent a halogen atom, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 7 carbon atoms, or an aryl group having 6 to 12 carbon atoms; and a and b each independently represent an integer of 0 to 4.

Abstract: An electrophotographic photoconductor includes a base, an undercoat layer that contains a metal oxide and an electron-accepting material and has a thickness of about 3 ?m or more and about 15 ?m or less, and a photosensitive layer containing a polymer having a repeating unit represented by general formula (1) where R1 and R2 each independently represent a halogen atom, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 7 carbon atoms, or an aryl group having 6 to 12 carbon atoms; and m and n each independently represent an integer of 0 to 4.

Abstract: An electrophotographic photoreceptor, includes: a conductive support; and a photosensitive layer provided on or above the conductive support, the photosensitive layer including an outermost surface layer at the farthest location from the conductive support, wherein the outermost surface layer contains: coated insulating inorganic particles obtained by subjecting insulating inorganic particles having a specific surface area of not more than about 300 m2/g to a coating treatment with an aromatic functional group-containing compound; and fluorine-containing organic particles.
