IPC: G03G15/08
Filed: 1991-03-14
Abstract: PURPOSE:To exactly detect a toner amt. and to prevent toner clogging by a localization by setting the falling supply rate of a developer to the part near a developer amt. detecting means larger than in the other parts in the longitudinal direction of a developing device. CONSTITUTION:The height of a screw wall 1 is lowered by as much as a prescribed value. The falling distribution of the toner in the longitudinal direction of the developing device is, therefore, made largest near a toner sensor. The toner supplied from a hopper is eventually transported as it is to a notched part D in such a case, but the amt. of the toner falling to the notched part D is so controlled as to be largest within the longitudinal direction regardless of environments by setting the height of the screw wall 1 after notching equal to or lower than the central axis of the screw. Namely, the toner transported to the notched part D is large in the amt. and therefore, the toner is forcibly dropped by specifically setting the height of the screw wall 1, by that, the fluctuations in the falling amt. of the toner by the environment are decreased.
