To accomplish high-speed fixing which requires high-precision temperature control, or fixing of high-quality color images on various kinds of paper without increasing the size and production cost of the temperature detecting means and contaminating the back sides of paper by toner that comes off from the temperature detecting element, an image forming device is equipped with a fixing device comprising a heating roller, a pressing belt which forcibly contacts the heating roller, and a temperature detecting means which touches the surface of the heating roller to sense the surface temperature of the heating roller, wherein a cleaning means to clean the belt surface is provided on a place which is corresponding to a place at which the contact-type thermistor touches the heating roller.

In a fixing apparatus including heating member having an elastic layer and a heat source and pressing member having an endless shape member and a pressing member for transporting a record medium in a cut sheet shape while being adhered with an unfixed toner image to pass a nip portion formed by the endless shape member and the heating member and fixing the unfixed toner image on the record medium, the fixing apparatus is constructed by a constitution in which a space between the toner image on the record medium and a surface of the heating member is widened immediately after the record medium is projected from an outlet of the nip portion.

An electronic color photography apparatus includes a photosensitive body and a plurality of detachable developing devices. A power for moving the developing devices close to the photosensitive body is created by a retracting force of a slanted teeth gear which is driven at one side of a body of the electronic color photography apparatus.

A fixing unit that is provided in an image forming device and fixes a toner image transferred to paper is constructed of two belts, belt guides each of which guides the inner periphery of each of the belts, a heating member arranged in one of the belts or heating members arranged in both of the belts, a drive roller for driving the inner periphery of the belt, wherein the belts pinch paper on both surfaces thereof by the belt guides and carry the paper. This construction can realize a fixing unit reduced in size and capable of printing images at high speeds and shortening a rise time that elapses until the fixing unit reaches a fixable temperature.

A paper sorting apparatus includes first to fourth gap measuring units to measure gaps between sheets of paper. Using the gaps between the sheets varying between the respective gap measuring units, target gap correction values are stored for respective sort shelves. In accordance with gaps between sheets changed between the first and second gap measuring units, there are predicted gap variations possibly taking place by when the sheets reach the associated sort shelves. Depending on the predicted gap variations, a gap adjuster is controlled to set the gaps to appropriate values at a point where the pertinent sheets reach the associated sort shelves.

An overlapped mail detection apparatus and method are disclosed. Since the postcard is shorter than the letter, the change in length is not sometimes detected even when the postcard is displaced. In the case where the exterior of the letter is deformed outward and an overlap is detected from the rise of the tail end of the letter after passing a guide, a thin letter or the like low in rigidity is hard to detect due to the slow rise after deformation in the guide. In view of this, a separator has a bent conveyance path for deforming the exterior of the letter outward. The conveyance surfaces constituting the inner and outer sides of the bent portion of the separator are spaced appropriately from each other. A detector detects the state of the letter surface in the neighborhood of the outer conveyance surface with which the forward end of the letter first comes into contact. An overlap of letters is judged from the result of detection by the detector.

An automatic code recognizing apparatus includes an arithmetic operation unit for calculating the distance from a barcode scanner to the upper surface center of an article to be detected and the distances from barcode scanners to the side surface centers of the article to be detected based on detection signals from a height sensor and a TV camera. A mirror is controlled to focus the focal positions of the barcode scanners on the upper surface center and side surface centers of the article based on the result of calculation of the arithmetic operation unit. With this arrangement, there can be provided the automatic barcode recognizing apparatus capable of recognizing a barcode with a pinpoint accuracy and excellent responsiveness.
