PURPOSE:To obtain good fine line reproducibility at a high density without fogging and to form copied images having high quality by dispersing and incorporating various additives into a binder resin having specific relaxation time, thereby adjusting the binder resin to the specific relaxation time. CONSTITUTION:The resin which independently exhibits the electric characteristic of 30 to 60msec. relaxation time at 100kHz frequency is used as the binder resin. The toner which is prepd. by mixing and dispersing the various additives, such as coloring agents, with and into the binder resin and has 8 to 20msec. relaxation time is used. The toner images stuck and formed on a photosensitive body in this case are faithfully transferred onto a transfer material without moving or liberating of the toner. The images of the high image quality are formed at the high density and the good fine line reproducibility without fogging in this way. |
