Abstract
PURPOSE:To make possible effective image formation by conveying the removed developer through the utilization of the movement of a restraining magnetic field without applying mechanical pressure. CONSTITUTION:A magnetic roller M having plural magnetic poles is rotatably disposed near the removed developer discharge outlet of a cleaning means and a counter magnetic pole plate CP is so disposed in opposition to the magnetic roller M as to form a slit-form passage of a minimum clearance d0. As a result of this, the removed developer removed from photosensitive drum by a cleaning means is force- fed toward the lower side of a guide plate G and is reused without being applied with any mechanical pressure as the revolution of the magnetic roller M causes its magnetic poles S1-S4 to subsequently approach to the counter magnetic pole plate CP and move while forming a restraining magnetic field through sharp increase in the magnetic field intensity then leave from the counter magnetic pole plate CP to weaken the restratining magnetic field. Hence, the image formation is accomplished efficiently.
