ABSTRACT:
The invention is directed to a developing method for electrophotography in which an insulating magnetic toner contacts an electrostatic image carrier to develop an electrostatic latent image. A magnetic bias is applied to restrain movement of the magnetic toner toward the image carrier and an alternating electric field is applied to the toner, all subject to the condition V/d.gtoreq.0.1.nu. in which V represents the effective voltage impressed upon the toner, d represents the clearance in millimeters between the image carrier and a developing sleeve, and .nu. represents the frequency in kilohertz of the alternating electric field.
