  • Patent number: 6577824
    Abstract: 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.

  • Patent number: 6226471
    Abstract: The main body of a digital copying machine is connected to a finisher. The main body subtracts a certain length of time from the sheet processing time designated by the finisher. Owing to this, even when the finisher is used, printing processing is executed with no need to decrease the processing speed originally provided for the main body of the digital copying machine.
