Abstract:
An image-forming method comprising the steps of:forming a layer of a developer on a surface of a developer support member disposed facing a latent image support member;developing an electrostatic latent image on the latent image support member using the layer of the developer formed to obtain a toner image;transferring the toner image onto a transfer material; andfixing the transferred toner image, wherein the developer support member has therein a development magnetic pole in which a magnetic force of a main pole is 100 mT or more, said developer having a toner and a carrier which has a volume average particle diameter of 50 .mu.m or less, an image formation method is conducted at a process speed of 200 mm/sec or more, and an electrical resistance of the developer when a toner concentration of the developer is 8% by weight is at least 10.sup.9 .OMEGA. and at most 10.sup.12 .OMEGA..
