摘要： An image forming apparatus includes a fixing unit and a fixing process managing system. The fixing process managing system, including a mode switchover unit, controls a time mode and a temperature mode for heating a fixing member. In the time mode, the fixing unit is determined to be ready for a fixing process when a given time elapses after activation of the image forming apparatus. In the temperature mode, the fixing unit is determined to be ready for a fixing process when a temperature of the fixing member attains a given reference temperature after activation of the image forming apparatus. The mode switchover unit selects between the temperature mode and the time mode. The fixing process managing system selects the temperature mode instead of the time mode when a supply amount of electrical power to the fixing unit is determined to be below a required electrical power supply level.

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 fixing device including a fixing unit that fixes a toner image on a recording material by application of heat and pressure, and a glossing unit that controls a gloss of the toner image fixed on the recording material. The glossing unit includes a heating roller, an endless belt stretched taut over multiple rollers including the heating roller, a pressing roller pressed against the heating roller with the endless belt therebetween to form a nip therebetween, and a separating member that separates the recording material from the endless belt downstream from the nip. The multiple rollers are positioned to maintain the recording material in contact with the endless belt for a predetermined distance downstream from the nip. The separating member is movable along the endless belt downstream from the nip, to control a length of contact between the recording material and the endless belt.
