Abstract
A carrier for electrophotography having a resin coating layer containing a conductive powder having an aspect ratio of not less than 3 on the core material, in which the dynamic electric resistance of the core material in a magnetic brush state under an electric field of 10.sup.4 V/cm is not higher than 1 .OMEGA..cm, and the electric resistance of the resin coating layer is within a range of from 10 to 1.times.10.sup.8 .OMEGA..cm, and a developer for an electrostatic latent image using the carrier. An image forming method on which the developing process includes using the above-mentioned developer for an electrostatic latent image, whose development curve, expressed by a contrast potential and the developing toner quantity, has a saturation area, and applying the developing bias to the developer carrying member so that the developing toner quantity shows the saturation characteristic.
