摘要： A fixing apparatus for controlling an oil transfer apparatus to maintain a releasing agent holding layer such that it is not always saturated with the releasing agent. This makes it a compact, cost-effective unit with a long service life and provides a uniform, stable oil coating that eliminates image noise problems. In order to use a constant and minimum necessary amount of releasing agent, a releasing agent supply nozzle is incorporated with multiple protrusive or retrusive droplet growth assisting members at or near multiple releasing agent discharge ports. The supply nozzle used for supplying the oil has multiple discharge holes having approximately equal opening cross-sectional areas and an equalizing member which equalizes the amount of oil discharged from each discharge hole. The outer diameter D1 of the oil supply roller, the outer diameter D2 of the metal core and the distance P of adjacent through-holes formed on the periphery of the metal core satisfy a relation, 0.6

摘要： A fixing device for thermally fixing an unfixed image onto a recording sheet by causing the sheet to pass through a fixing nip. The fixing device includes: heat belt formed in an endless shape and provided with a resistance heat layer; first pressure member provided inside a running path of the heat belt; and second pressure member pressing the first pressure member from over the running path to form the fixing nip. At least one of the first and second pressure members is rotating body. The heat belt has a pressure-receiving area and two non-pressure areas. The pressure-receiving area receives pressures from both the first and second pressure members. The non-pressure areas have been arranged at outside of the pressure-receiving area in an axis direction of the rotating body. Two ring-like electrodes have been formed on circumferential surfaces of the non-pressure areas and are used to supply power to the resistance heat layer.
