摘要:
In an image forming apparatus, a developing unit for forming an image by use of a two-ingredient type developer, i.e., toner and carrier mixture, includes a container for replenishing fresh toner and for replacing carrier deteriorated due to aging or a developer including such carrier. The developer in the developing unit will be collected based on the number of times that a part of the developer has been replenished.
