摘要:
The present invention provides a developer which is comprised of the magnetic toner having the specific binder resin component and low-molecular weight wax and the additives of the fine silica powder, metal oxide powder and fluorine-containing fine resin powder which are used in combination in given amounts. Hence, it is possible to prevent the melt-adhesion of toner to the surfaces of the contact charging member and contact transfer member, to cause no faulty images and to obtain images with the enjoyment of superior low-temperature fixing performance and anti-offset properties, even when copies are taken on a large number of sheets using the image forming method having contact charging and contact transfer systems.
