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： In the head-fixing apparatus of the film heating system in an image forming apparatus, a heat capacity is controlled to be as small as possible because the quick-start property is recognized to be more importance. Thus, heat conductivity in the longitudinal direction is poor and, due to a relationship between the area where a recording material is conveyed and the heating area of the energizing heating resistance layer, a) heat is insufficient at the end portion in the initial period and b) unusual temperature rising occurs at the end portion at the time of continuous heat-fixing. In order to resolve those problem, an apparatus which can control adequately temperature at the area where a recording material is conveyed without rising temperature at the end portion of a heater as a non-sheet passing area.

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.
