Abstract: A fixing device includes a fixing rotator, a heat source, a controller, a pressure rotator, and a nip formation pad. The controller controls the heat source such that a temperature of the fixing rotator is equal to a preset fixing temperature. The nip formation pad abuts the pressure rotator via the fixing rotator and forms a nip between the fixing rotator and the pressure rotator. When a print time of a previous job is longer than a prescribed time A and a next job is started within a prescribed time B after an end of the previous job, the controller corrects the preset fixing temperature during a time from a start of the next job to an entry of a print sheet into the nip and during a time from the entry of the print sheet into the nip to a lapse of a prescribed time C after the entry.

Abstract: According to one embodiment, contactless power transfer apparatus includes: transmission coil; primary capacitor; reception coil opposing transmission coil through gap; and secondary capacitor. Specification of frequency of the transmission coil and that of the reception coil are equal. At least one of electrical power specification and gap length specification of the transmission coil differ from the reception coil. When the electrical power specification of the power transmission coil differ from that of the power reception coil, the power is supplied from the transmission coil to the reception coil by using smaller one of the power of the transmission coil and of the reception coil as maximum power. When the gap length specification of the transmission coil differs from that of the reception coil, the transmission coil opposes the reception coil through the gap length, which is the specification of the transmission coil.
