Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for preventing a paper trailing edge printing from being deleted which can handle a paper so that components for forming images can move in proximity to the paper without any obstruction. SOLUTION: A biasing member 600 can firmly hold the paper on a paper path to a paper guide 610 by communicating with the paper guide 610. A printer 630 is enabled to contact the paper 620 near the trailing edge of the paper 620. The biasing member 600 applies a bias to the paper guide 610, preferably applies a force to the paper guide 610 so that the paper 620 is stretched tight to a farther point along the paper path. Images can be formed normally on the paper 620 with the use of the printer 630 by maintaining the paper 620 in the stretch state.

Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for improving alignment between color resolved images. SOLUTION: By controlling the output of image data and the speed of an image carrying member for every one or more color resolved images based on the measured position and speed of the image carrying member, the deviation of the alignment is eliminated or reduced. A position measuring sensor 352 on an image carrying member device module is used to measure the position of the image carrying member in a processing direction and provides movement information in real time. A position measuring controller 248 detects the pattern of a position measuring mark by using the sensor 352 and processes the data detected by averaging and correlating in order to eliminate a detection error, whereby the position of the image carrying member in the processing direction is decided.

Abstract: PROBLEM TO BE SOLVED: To prevent the size of copying paper from being changed by heat and pressure at a fusing and fixing time or a transferring and fixing time, to prevent the size of an image from being changed in accordance with it and to accurately register the image. SOLUTION: The preliminary adjustment device (PSPA) 204 of a blank paper base is included in order to change and stabilize the size of one part 64 of a paper base before it is supplied to transferring and fixing stations 29, 39, 49 and 59. The PSPA 204 includes a heating/pressuring device preliminarily heating/pressuring one part 64 of the paper base so as to change the size thereof to such an extent that it cannot be changed even heat and pressure are added by the heating/pressuring device at the fusing and fixing time of a back stage.
