Abstract
A toner replenishing apparatus capable of, without increasing a drive torque for rotating the toner replenishing container, scraping toner adhered in a toner replenishing container to reduce the quantity of residual toner that remains unfed from the toner replenishing container, is provided. The toner replenishing apparatus includes a toner replenishing container for replenishing toner stored therein to a developing section by rotation of the toner replenishing container, a magnetic body movably provided in the toner replenishing container, and a magnet disposed closely to an outer peripheral surface of the toner replenishing container and attracting the magnetic body with a magnetic force.
Claims11
A toner replenishing apparatus for replenishing toner to a developing section which develops with toner an electrostatic image on a surface of a photoreceptor drum, comprising:
- a toner replenishing container formed into a cylindrical shape, for replenishing toner stored therein, to the developing section by rotation of the toner replenishing container;
- a magnetic body movably provided in the toner replenishing container;
- and
- a magnet disposed closely to an outer peripheral surface of the toner replenishing container, and attracting the magnetic body with a magnetic force, wherein the magnet is provided so as to be movable along a direction in which an axis of rotation of the toner replenishing container extends.
