ABSTRACT:
A developing device for a copier is controlled such that if the rate at which toner is supplied into its developing tank is detected to exceed a preset reference value, stirring rollers for stirring the toner inside the developing tank are caused to rotate at a slower rate than if the toner supply rate is detected to be less than the reference value such that toner can be charged sufficiently in spite of its increased rate of supply and an image of good quality can be obtained.
