Abstract
PURPOSE:To agitate sufficiently in the longitudinal direction of the toner replenishing mechanism, by constituting so that the scraped-off toner may be recovered by dropping into a developing device or toner replenishing tank almost in uniform volume each in the longitudinal direction thereof. CONSTITUTION:A photosensitive drum 1 rotates in the direction of arrow. The toner is scraped off from the photosensitive drum 1 by means of a blade 4b of a cleaning device 4, and is swept off into the bottom of a box 4c by a roll brush 4a. The toner passes through a tube 14 by way of a rotating helical coil 13 provided on the upper opening of a tube 12, and is conveyed to an end part 14a. Wedge-form holes 19 increasing in the width towards the longitudinal direction or circular holes 19 increasing gradually in the radius are provided in the bottom plate 14b of the end part 14a provided in the longitudinal direction of a developing device 2 or replenishing tank, and the toner is, while being conveyed by the helical coil 15, dropped off by almost uniform volume each in the Iongitudinal direction of the developing device 2 or replenishing tank 20, so that sufficient agitation may be achieved.
