Developing process excellent in image reproducibility.

摘要

A developing process excellent in reproducibility of images is disclosed. In reproducing multiple fine lines,the line width can be kept uniform in the respective lines and front end chipping or rear end chipping can be prevented, and a high-density and high-quality image can be formed, by carrying out the sliding contact between the magnetic brush of the developer and the surface of the photosensitive material so that the frequency of the contact of a carrier with the photosensitive material is set within a certain range; or establishing a specific relation among the speed rotation of the developing sleeve, the saturation magnetisation of the magnetic carrier and the flux density of magnetic poles in the developing sleeve or further setting the contacting frequency of the carrier within a certain range. <IMAGE>
