摘要： An image formation apparatus is disclosed. The image formation apparatus includes a fixing unit whose heater temperature is controlled to be in a non-offsetting range so that no offset is produced, the non-offsetting range being defined for each different paper thickness. Nip time remains constant even when the thickness of the paper to be printed on next is changed. Printing is suspended until the heater temperature, approaching the non-offsetting range, reaches an inconspicuous offset range on either side of the non-offsetting range, inconspicuous offset being produced if printing is performed in the inconspicuous offset range.

摘要： The fixing device includes a fixing unit, a pressure unit that comes into pressure-contact with the fixing unit to form a nip, and control guides. The fixing unit includes a heat roller. The pressure unit includes a pressure belt, and a pressure pad. The pressure pad is attached to a holder and pressed by a spring through a stay, thereby bringing the pressure belt into pressure-contact with the heat roller. The control guides on both sides of the pressure pad control deformation of the pressure pad in an axial direction of the heat roller to make a nip shape uniform.

摘要： A pressurizing unit includes a contact-pressure member for pressurizing an endless belt, a holding member that holds the contact-pressure member, and a biasing member that presses both ends of the holding member. The biasing member presses the holding member, so that a direction in which the biasing member presses the holding member is substantially the same as a direction in which the holding member presses the pressure-contact member.

摘要： In a fixing apparatus, an internal temperature detection device is arranged within a heat generation region and detects temperature of a fixing device. An external temperature detection device is arranged at the outside of the heat generation region and detects temperature of the fixing device. Heat generation in the heat generating device is stopped when temperature reaches a prescribed first high temperature detection limit and a temperature rising amount in a prescribed time period after the first high temperature detection limit is reached exceeds a prescribed threshold.
