ABSTRACT:
An optimum image can be obtained by carrying out the development while using a two-component type developer comprising an electroscopic toner and a magnetic carrier and maintaining the peripheral speed ratio of the magnet sleeve to the photosensitive material drum within a certain range according to the average particle size and saturation magnetization of the magnetic carrier and the dynamic friction coefficient of the magnetic brush.
