A process for developing a latent image with a developer is provided which comprises (1) forming a layer of a developer comprising a magnetic toner containing magnetic powder having a BET specific surface area of 2 to 20 m2/g on a member for supporting the developer, (2) bringing an electrophotographic photosensitive member holding the latent image into contact with said developer layer, said electrophotographic photosensitive member comprising an organic photoconductive material having a surface hardness more than 10 g, (3) forming a toner image on said electrophotographic photosensitive member, (4) transferring the toner image onto the transfer material, and (5) cleaning the electrophotographic photosensitive member having passed through the transferring step with a cleaning member. Said developer may alternatively comprises magnetic particles containing a binder and magnetic powder having a BET specific surface area of 2 to 20 m2/g, and a non-magnetic or magnetic toner on a member for supporting the developer.
