<p>PURPOSE:To obtain such an electrostatic charge image developing toner that even when the toner is used in a system to recover a waste toner and to reuse the recovered toner in the developing process, high reflection image density can be always maintained even for lots of copies and picture images without fog or splashing of toner can be obtd. CONSTITUTION:The electrostatic charge image developing toner is used for such an image forming method that a latent image on a latent image carrier body is developed to form a toner image, the toner image is transferred from the latent image carrier body to the transfer member, the latent image carrier body after transfer is cleaned to recover the toner remaining on the carrier body, and the recovered toner is supplied in the developing zone to be used for the development. The electrostatic charge image developing toner contains at least a binder resin and coloring agent. The mol.wt. distribution of the resin component by gel permeation chromatography(GPC) shows Mw/Mn>=100, wherein Mw is the weight average mol.wt. and Mn is number average mol.wt.</p> |
