摘要： The present invention provides a method for impression development which comprises forming a thin layer of a toner on a surface of a developing roller with a plate-like rigid member, and developing an electrostatic latent image formed on a photoconductor by contacting the thin layer with the electrostatic latent image. The toner comprises toner particles, and prescribed amount of inorganic fine particles (mean particle diameter of 0.1 to 1.0 .mu.m on the volume basis), and/or comprises toner particles which have prescribed distribution of the odd-shape degree of the toner particle (mean value of the odd-shape degree and the proportion of the number of toner particles having the odd-shape degree of not more than 0.2). According to the method for impression development, it becomes possible to form an image having no failures and good image quality.

摘要： Disclosed is a toner comprising a fixing resin, a colorant, a releasant made of a polyolefin having a melting point of not more than 120.degree. C., preferably 60 to 120.degree. C. and a compatibilizing agent for the fixing resin and the releasant, wherein a glass transition temperature Tg of the toner is from 53 to 63.degree. C. and the releasant having a particle diameter of 0.2 to 1.5 .mu.m is dispersed in the fixing resin. This toner is superior in blocking resistance, filming resistance and the like and is capable of fixing at a low temperature and, therefore, this toner is useful as a toner for image forming apparatus utilizing an electrophotographic process.
