摘要:
A developing method including the steps of: stirring a two component-type developer which contains a toner and a carrier; conveying the developer to a developing section with a conveying screw and a developer carrying member; and developing an electrostatic latent image on an image holding member by forming a magnetic brush on a developing magnetic pole, wherein the carrier is a magnetic material dispersion-type resin carrier containing a binder resin and a metal oxide, has a low coercive force and has been previously exposed and magnetized in a specific magnetic field and has stable residual magnetization, thereby imparting a high durability to the developer and making it usable for a long time to reproduce a large number of images having stable qualities.
