Abstract

PURPOSE:To develop clearly even under high-humidity or low-humidity conditions by using a one-component isulating toner without using any carrier by containing an apliphatic F-containing compound and an organic silicone polymer on the surface of a member (sleeve, etc.) which gives triboelectrification to a toner. CONSTITUTION:For instance, when a one-component insulating magnetic toner is applied to the development of electrostatic latent image, to the nonmagnetic cylinder surface 4b, a surface layer containing an organic silicone compound and an aliphatic F compound is given by forming the surface layer using liquid dispersed polytetrafluoroethyene and solid phenyl silicone vernish and polyurethane in toluene, etc., and so on. Thus, the charging of a toner 11 is improved and even if copy is repeated a clear image is avaible and especially, a phenomenon that after copying a lot of small originals such as A4 size with one-component insulating toner, if a large original in B size or the like is copied the image density in an extended margin part becomes low can be dissolved.
