摘要： The present invention provides an image forming system in which an image of a document can always be printed in an appropriate position of paper with reliability even when a scanning magnification of the image is changed. The system therefore includes a scanner for scanning a document image to generate an image signal, a printer for forming a copying image on paper in response to the image signal supplied from the scanner, a paper feeding section for feeding the paper to the printer, a magnification setting section for setting a scanning magnification when the scanner scans the document image, and a timing control section for controlling timing of supply of the image signal from the scanner to the printer and/or timing of supply of the paper from the paper feeding section to the printer such that the size of a margin between the leading edge of the paper and that of the copying image formed on the paper is fixed irrespective of the scanning magnification.

摘要： A technique that can perform appropriate image quality control processing corresponding to fluctuation in a printing environment is provided.An image forming apparatus that forms, on a sheet, a test pattern formed by a color obtained by mixing toners of plural colors, scans a test pattern image formed on the sheet with a color sensor, and performs predetermined image quality control processing on the basis of information scanned, the image forming apparatus including a media sensor that acquires information for discriminating a type of a sheet to be an object of image formation processing, a control-information acquiring unit that acquires, on the basis of the information acquired by the media sensor, information for control used in the image quality control processing, and a color sensor that is arranged further on a downstream side than a fixing device in a sheet conveying direction and scans the test pattern formed on the sheet.

摘要： When a monochromatic copy mode is to be executed, a control section sets a read mode in a scanner section so as to enable the scanner section to read an image at high speed by means of only a line sensor K, sets in an image processing section an image process that can print monochromatic image information, which is sent from the scanner section, with a single black color in the printer section, and sets in the printer section a monochromatic print mode that can print a black image at high speed, thereby controlling a monochromatic copy operation.
