Inventor: KOIKE TOSHIO
IPC: G03G15/08
Filed: 2000-11-01
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing the lowering of image density caused by the faulty replenishment of toner and the adhesion of carrier to an image carrier. SOLUTION: A vent 16 is provided on the upper surface part of a toner hopper 8 and communicates the inside and the outside of the hopper 8 as shown by a thick arrow in figure, so that air is taken in and out. Thus, pressure reduction in the hopper 8 is avoided because outside air gets into space in the hopper 8 through the vent 16 when the seal member of a toner replenishing port 8a is pulled out and detached at initial using time. Therefore, pressure to lead toner 11 toward the inside of the hopper 8 from the port 8a side is not generated on the toner 11, so that the toner 11 flows in the port 8b and is sufficiently supplied to a developer retaining part 3b before a pre-doctor blade 6b.
