摘要： PURPOSE:To extend a temp. range in which a toner can be fixed and to raise the thermal aggregation temp. of the toner by using a binding resin formed by mixing a low mol. wt. polymer of a vinyl monomer with a high mol. wt. polymer of the vinyl monomer in a specified ratio so that the chromatograph of the resin has one max. value in each of specified mol. wt. ranges. CONSTITUTION:A binding resin is formed by mixing a low mol. wt. polymer of a vinyl monomer with a high mol. wt. polymer of the vinyl monomer in 50:50-10:90 ratio so that the chromatograph of the resin measured by a gel permeation method has one max. value in each of the mol. wt. ranges of 3,000-5,000 and 150,000-2,000,000. Since the low mol. wt. polymer is present in the binding resin, min. fixing temp. and fixing nip pressure can be reduced and grindability is improved. Since the high mol. wt. polymer is present in the binding resin, anti-offsetting property can be rendered to a toner. A temp. range in which the toner can be fixed is extended and the thermal aggregation temp. of the toner is raised.

摘要： PURPOSE:To improve stability and printing resistance of the titled layer by vaporizing a liquid hydrocarbon compd. at normal temp. and pressure, and introducing the obtd. gas to a vacuum system, followed by forming a coating layer on an aluminum substrate with a vapor grown film. CONSTITUTION:The aluminium substrate 2 is mounted on the supporting body of a lower electrode in a plasma polymerization apparatus, and the substrate is heated to a substrate temp. of 300 deg.C by a heater 4, after reducing the pressure of a bell jar to Torr. While heating the substrate, argon gas is introduced into said apparatus, followed by glow-discharging the substrate whereby the surface of the aluminium substrate is cleaned by an ion-bombardment. Next. the introduction of the argon gas is stopped, and the apparatus is reduced to the pressure of Torr, and a needle value 8 is opened, and benzene vapor is fed to the apparatus, followed by glow-discharging the substrate at the vacuum of 1.2X10 Torr. After 5hr, the substrate provided with transparent carbon film having 10mum thickness is taken out from the apparatus. The obtd. carbon film is charged to positive, and is image-wisely exposed by radiation of UV rays, followed by developing it with a two component magnetic brush developer. Thus, the good image having high stability, printing resistance and long shelf-life is obtd.
