Developing apparatus.

摘要

A developing apparatus comprises a hopper (2) in which a developer is stored; an electrostatic latent image carrier (13) to which the developer is supplied; a supply roller (4) disposed to the hopper for supplying the developer stored in the hopper; and a developing roller (6) disposed to the hopper and contacting the supply roller for supply the toner supplied from the supply roller to the electrostatic latent image carrier. A developing blade (8) is brought into contact with the developing roller under pressure for thinning the developer laid on the developing roller, and a restriction member (20) is provided midway in a route through which the developer is delivered from the hopper to the supply roller for restricting the amount of the developer to be delivered to the supply roller.
