More Information
Summary: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. By rotating the container in one direction, both fresh toner and a two-ingredient developer can be supplied to the developing unit. Initially when a container is mounted, the developer is fed in an amount less than an amount for image formation to start and only when a second container is mounted and rotated is the developer amount sufficient for image formation to start.
