摘要： A heater has a top-surface layer made of an imide-based resin formed on an electrical insulation layer. The heater can generally used for an image heating apparatus incorporated in an image forming apparatus. Since the top-surface layer has preferable sliding and insulating characteristics, the heater provides good heat efficiency and durability.

摘要： In an image heating apparatus, a film has one face in sliding contact with a heater having a heat generating portion on a substrate. The other face of the film contacts a recording material bearing an image. The film moves with the recording material and the image on the recording material is heated by heat generated by the heater which is transmitted through the film. A temperature detecting element detects the temperature of the heater. The heat generating portion of the heater has a first heat generating portion and a second heat generating portion on the downstream side of the first heat generating portion with respect to the moving direction of the film. The middle of the temperature detecting element is positioned at the upstream side of the middle between the first and second heat generating portions with respect to the moving direction of the film.

摘要： Energy consumption in a fixing process of an electrophotographic image-forming apparatus is reduced. An unfixed toner image T1 is fixed on a recording medium by applying a photopolymerizable composition D1 to the unfixed toner image T1 formed on the recording medium and then performing irradiation with light having a maximum emission wavelength in a wavelength range of from 420 to 470 nm using a light emitting diode or an organic EL device for curing the photopolymerizable composition D1 by photopolymerization.

摘要： In continuous printing operation which repeatedly sets a state in which when a preceding printing material passes through the nip area of a thermal fixing unit, a succeeding printing material has been supplied to an image forming unit and image forming operation has been started, a first temperature indicating an ambient temperature near the thermal fixing unit is measured at an early time point in the continuous printing operation. A second temperature indicating the temperature of the printing material which has passed through the press contact nip portion at a predetermined period of time during the continuous printing operation is measured. The amount of heat to be supplied to the succeeding printing material is controlled on the basis of the measured first and second temperatures.

摘要： An image forming apparatus comprises a fusing device for heating and fixing an unfixed image on a recording material while feeding the recording material, reversing device for reversing the recording material after passing the fusing device. The image forming apparatus operates in a first mode in which the recording material which passed the fusing device is ejected to an ejection section directly without being reversed, and a second mode in which the recording material which passed said fusing device is ejected to an ejection section after being reversed by the reversing device. A throughput of the recording material fed and/or the fusing temperature of the fusing device in the first mode being smaller or lower during at least part of an image forming process than in the second mode. With this image forming apparatus, the recording materials can be stacked in the ejection portion with improved quality and an excessive rise of temperature in the vicinity of the ejection portion can be avoided.

摘要： The invention relates to a display processing apparatus which may be used in instances when a single display is to be used to represent multiple parameters whose values may be correlated or interrelated with one another. The invention is particularly useful when simultaneously displaying a plot of position vs. time and some other parameter whose value changes with position, time, or both. Correlative display is made possible by a technique which samples the values of all of the related parameters at intervals, and stores the sampled values along with an indication of the elapsed time. In this manner, positional or other parametric data corresponding to distinct points or ranges of time can be extracted and displayed in time-correlated fashion.
