Abstract

PURPOSE:To eliminate the phenomenon by which the image density of widened parts is decreases at the time of copying a large size after copying of multiple sheets of small sizes by containing polyphenylene oxide in the surface layer of a member which applies friction charge to the one-component insulation-characteristic toner. CONSTITUTION:The one-component insulation-characteristic magnetic toner 11 is used, and the toner 11 is adhered thinly by means of a blade 10 on the developing device which is formed with a thin surface layer contg. polyphenylene oxide on the surface 4b of a nonmagnetic cylinder (made of Al etc.) fixed with a multipole permanent magnet. Thereby, the latent images are developed by the charged toner 11. The phenomenon by which the parts of increased size width were hitherto not well developed when large-size developing is made after repetition of multiple times of developing of small sizes is eliminated and always good images are obtainable.
