Abstract: PURPOSE:To provide a sufficient tolerance for dispersion of the gap between a developing sleeve and a photoreceptor or a regulating member and to stabilize picture quality by setting the developer dynamic resistance as well as the peripheral speed difference between the developing sleeve and the photoreceptor within respective specific ranges during development. CONSTITUTION:A two-component developer 6 composed mainly of a toner 18 and a carrier is stirred and mixed by two stirring members 3, 4 and is then attracted to a rotatable developing sleeve 5 having a permanent magnet disposed therein, and is regulated to a certain layer thickness by a regulating member 9 and then a magnetic brush is formed so that an electrostatic latent image on a photoreceptor 10 is made visible. In this case, when the moving speed of the developing sleeve 5 is Vdmm/sec and that of the photoreceptor 10 Vpmm/sec, the peripheral speed difference Vd-VP of the developing sleeve 5 and the photoreceptor 10 is held almost constant regardless of changes in the moving speed of the photoreceptor 10. Two-component developer 6 with a dynamic resistance of 1X10<8>-1X10<11>OMEGAcm is used. Therefore, development is carried out while the peripheral speed difference as well as the developer dynamic resistance, both of which could greatly affect picture quality, are set within respective proper ranges.
