Apparatus and method for supplying new and recovered toner to a developing device

摘要

An image forming apparatus and method cause a connecting/conveying device to convey a recovered toner from a cleaner part to a recovered toner housing to house therein the recovered toner, and cause a control device to separately control a recovered toner supply device and a new toner supply device to supply the recovered toner, which is stored in the recovered toner housing, and/or a new toner, which is stored in a new toner housing, to a developing device. The control device restricts the supply of the recovered toner from the recovered toner housing to the developing device when a no-residual-amount detecting device detects no residual amount of the new toner in the new toner housing.
