Abstract
Prior to execution of a printing operation and in parallel with a warm-up operation of the apparatus, a print preparatory operation is conducted only on selected cartridges of cartridges mounted to a developing unit, thereby bringing the cartridge into a printable state. Therefore, even if the residual amount of toner in one of the selected cartridges runs short, the printing operation is allowed to continue by switching this cartridge to the next selected cartridge.
