摘要:
An image-forming apparatus is disclosed. The image-forming apparatus includes a fixing unit. The fixing unit includes: a heating part including a heating element; a power storage unit including a chargeable and dischargeable capacitor and supplying power to the heating part so that the heating element of the heating part generates heat; and a controller controlling the operation of the power storage unit. When the image-forming operation of the image-forming apparatus is suspended by an abnormality, the controller performs control such that the capacitor is charged in accordance with its remaining amount of stored energy.

摘要:
Power is supplied from a capacitor of an auxiliary power source to a secondary heating element of a heating unit, thereby preventing temperature drop of a fixing roller at the time of continuous paper delivery. An allowable range for starting discharge from the capacitor is set to, for example, 30 to 40 volts. A discharge time in which the voltage of the capacitor reduces to a termination value, such as 20 volts, is longer than a time necessary for a reading unit to read a maximum number (for example, 100 sheets) of documents that can be read at one time.

A heater is operable with a main power supply unit and a chargeable auxiliary power supplying unit. The heater includes a heater part having one or a plurality of heater elements to receive power from the main and auxiliary power supplying units, a detecting part to detect information related to the heater part, and a controller to vary an amount of power supplied from the auxiliary power supply unit to the heater part per unit time based on the information detected by the detecting part.

A heater operable with main and auxiliary power supply units. A controller selects a first mode to permit discharge of the auxiliary power supply unit when a voltage or power from the auxiliary power supply unit is a startable value or greater without making reference to judgment information, or a second mode to permit discharge of the auxiliary power supply unit based on the judgment information when the voltage or power from the auxiliary supply unit is less than the startable value.
