Abstract: When an input image is to be formed on a sheet conveyed to a transfer roller, the exposure section is controlled and deviation correction is performed to offset the image forming position across the width of the sheet in response to the result of detection by a deviation sensor. By contrast, when pattern images are to be formed on a sheet in response to the instruction of the main control section, the image forming control section does not perform deviation correction in the process of forming a pattern image.

Abstract: While a recording sheet is passing through a fixing nip formed between a heating roller 41 having a heating layer and a pressing roller 42 pressed against the roller 41, a coil 43 is exited by high-frequency power from a power source and causes the layer to generate heat. An unfixed image on the recording sheet is fixed by the heat. The power source detects a zero cross timing of a rectified alternating current, detects an instantaneous value at a point a predetermined period after the zero cross timing, calculates an effective power of the alternating current based on the instantaneous value, and controls the output power to be a desired value determined based on the effective power and the surface temperature of the roller 41. Thus power input to the power source can be quickly detected and power output to the coil can be quickly and stably controlled.

Abstract: A multi-functional copying machine according to the invention has a scanner for reading the image of a document and image information appended to the document and a printer for forming the image on a medium. It compares the image read by the scanner and the image information, determines according to the extent of alteration of the image whether or not reproduction of the image of the document as it is can be permitted and, if permitted, produces a copy from the reproduced image of the document.
