摘要： PURPOSE:To obtain stably vivid visible images of a sufficient image density for a long period by allowing a toner to contain a binder resin and a release agent whose penetration is lower than a prescribed value. CONSTITUTION:A carrying belt 20 which is moved along a passage reaching a toner receiving and distributing device 12 of a developing device 9 by rolls 22 and 23 is stretched on the outside peripheral face of a rotary drum 19. The toner gathered from the surface of the photosensitive drum 19 by a cleaning device 10 is sent to a recovery drum and is supplied to the toner receiving and distributing device 12 of the developing device 9 and is used for development of an electrostatic latent image on the photosensitive drum 19 again. This toner contains the binder resin and the release agent whose penetration is

摘要： PURPOSE:To prevent toner filming on an electrostatically charged image carrier, and clean it sufficiently and form an excellent image many times by coating the surface of the image carrier with a lubricant consisting of setting castor oil. CONSTITUTION:Solid matter of the lubricant W consisting of setting castor oil held on a holding member 11 is brought into contact with the outer circumferential surface of the image carrier 2 while suppressed by a spring 3 to coat the surface with the lubricant W in a thin layer. Consequently, a developer is prevented from sticking on the surface of the image carrier 2, and residual toner is cleaned by sufficiently to form an image many times.

摘要： PURPOSE:To obtain a toner having excellent offsetting property by incorporating a binder resin contg. a polymer polymerized with a polymerizable monomer in the presence of a reactive prepolymer and polyolefin wax which is block- or graft-coplymerized with an arom. vinyl monomer into the toner. CONSTITUTION:A binder resin contg. a polymer (an unreacted prepolymer may remain) obtd. by bringing a polymerizable monomer having a functional group that can react with functional groups in the presence of a prepolymer having the reactive groups such as -COOH, ethylene oxide, etc. at the main chain and 1 or side chain is manufactured. On the other hand, the modified wax formed by graft- or block-polymerizing a styrene monomer with polyolefin wax is manufactured. A toner in which the wax is incorporated at 10-20wt% in the mixture composed of the above-described resin and the wax is manufactured. The toner having a low fixing temp., a high offset generating temp., good fluidity and is hardly flocculate is thus obtd.
