Abstract

A developing apparatus uses a dual-component developer containing a magnetic carrier and toner electrically attracted to the magnetic carrier for selectively transferring the toner to an electrostatic latent image formed on an image support for visualizing the latent image. The developing apparatus includes a developer transport member facing the image support and having a peripheral surface for supporting and transporting the developer. A toner excess supplying member supplies excess toner to the developer supported on the developer transport member. An excess toner separator separates toner having a small adhesion force to the carrier from the developer to which excessive toner is applied.
