摘要： An image forming apparatus includes a latent image bearer; a developing device containing two-component developer and including a developer bearer, a development voltage source, and a toner concentration detector; a toner supply device to supply toner to the developing device; a transfer device; and a controller to keep a toner concentration in the developer in the developing device at a target toner concentration during image formation. The controller executes forced toner consumption in which the developing device supplies the toner to the latent image bearer the toner at a predetermined forced toner consumption timing, while inhibiting the toner supply device from supplying toner. When the toner concentration falls to a prescribed toner density lower than the target toner concentration, the controller completes the forced toner consumption and executes a post-consumption toner supply operation.

摘要： A processor, a memory medium for storing an operating system (OS) to be executed by the processor, one or more devices which are re-initialized upon OS restart, an active OS, and a standby OS are provided. The active OS is executed at system startup to initialize the devices, and executes an OS process in a normal state after the system startup. The standby OS is executed at system startup to detect the devices connected to the processor, and initialize the detected devices, and goes to standby. When an abnormality occurs in the active OS and a restart is needed, the standby OS re-initializes the devices by using re-initialization data for the devices which had been stored during the initialization process before going to standby.
