Claims

[Scope of utility model registration request]

Photosensitive drum of dry type electronic copying machine! The magnetic roll and blade are arranged so that the outer periphery is close to the circumferential surface and are driven to rotate, and are covered by a hopper and are arranged in the gap between the m-line of the cylinder (with a blade arranged to adjust the amount of toner to be sent out). In the hopper, one edge of the magnet roll is in contact with the inside of the blade or the member to which the blade is attached, apart from the gap between the magnet roll and the blade, and the other edge of the magnet roll is further away from the gap between the magnet roll and the blade. A developing device in which an electrically insulating net is installed inside the hopper, close to the outer circumferential surface in the axial direction, and the ends perpendicular to both edges extending to the inside of the hopper.
