PURPOSE:To prevent scratching of a photosensitive body and toner adhesion to it and to enhance cleaning aptitude by adding a fine silicone resin powder to the outside of the toner. CONSTITUTION:The fine silicone resin powder is added to the outside of the toner, and this powder is attached to the surface of each toner particle and intruded between each other. When a cleaning blade is rubbed in a considerable pressure with the surface of the photosensitive body having this toner composition attached, a friction coefficient is effectively alleviated by the excellent lubricity of the silicone resin, thus permitting the toner remaining on the surface of the photosensitive body to be smoothly ranked off without scratching its surface, and melt attaching of the toner to be avoided, and these effects to be obtained even under unfavorable environments of high temperature and high humidity. |
