    摘要： The invention relates generally to processes for electrostatic image development, and setpoints that provide uniform image development. In particular, an apparatus and process having a magnetic brush that implements hard carriers and a rotating magnetic core within a shell is disclosed. The process implements one or more of the following optimum setpoints: a range of shell surface speeds that provide uniform toning density, a range of shell surface speeds that prevent toner plate-out, a skive spacing that minimizes sensitivity to variation, a magnetic core speed that minimizes sensitivity to variation, and an imaging member spacing that minimizes sensitivity to variation.

    摘要： An image forming apparatus of the present invention includes a developing device including a rotatable, nonmagnetic developer carrier and a magnetic field forming device. In a developing region where the developer carrier faces an image carrier, the magnetic field forming device causes a developer made up of toner and magnetic grains to rise on the developer carrier in the form of a magnet brush. In the developing region, the magnet brush on the developer carrier is caused to move at a higher speed than the surface of the image carrier in the same direction as and in contact with the surface of the image carrier, thereby developing the latent image. The toner of the developer is magnetic toner. Flux density set up in the developing region outside of the surface of the developer carrier in a normal direction has an attenuation ratio of 50 % or above.

    摘要： An image forming method is disclosed. The method comprises steps of supplying developer (50) onto the surface of a developing roller (141) having a high magnetic field not less than 1000 G at the surface thereof, and making color superposed images on an image carrier (1) by repeating twice or more the step of non-contact-developing a latent image formed on the image carrier through an oscillating electric field formed between the developing roller and the image carrier. A carrier in the developer has a volume average particle size of not more than 50 µm and the saturation magnetization amount σ S of the carrier particles is not more than 50 emu/g. A toner having narrow particle size distribution is preferably used.
