Abstract: Prior to reading an original image, whether to read the original image in a monochrome image mode in which the image reading apparatus reads the original image in use of the monochrome line sensor or a multi color image mode in which the image reading apparatus reads the original image in use of the multi color line sensor is predicted. Preparation of reading an original image based on parameters corresponding to the predicted mode is completed before the start of reading the original image. This arrangement reduces a time loss arising from switching of a color mode associated with a user color setting at the start of a job, and thus shortens the FCOT. This arrangement can shorten the time until the first copy is output after designating the start of copying when reading an original image based on different parameters.

Abstract: In reading an image of a document in a monochromatic document reading mode, a document reading apparatus reads the image of the document while conveying the document at a speed determined according to a variable magnification ratio, executes digital variable magnification on the read multivalued image in a main scanning direction by using a main scanning direction variable magnification unit, binarizes the multivalued image, and stores the binary image on a memory. In reading an image in a color document reading mode, the document reading apparatus reads the image of the document while conveying the document at a predetermined speed, stores the read multivalued image on the memory, and executes digital variable magnification on the multivalued image in the main scanning direction and a sub scanning direction.

Abstract: An image forming apparatus that is capable of carrying out image formation on a recording medium such as plain paper without increasing the FCOT (First Copy Out Time) and is also capable of carrying out optimal image formation on a recording medium, such as thick paper, for which the processing speed is reduced with no registration misalignment between the leading ends of toner images and the leading end of the recording medium. An image is primarily transferred onto a rotatively driven image carrier, and the image on the image carrier is secondarily transferred onto a recording medium. An image writing reference position signal for starting image formation is issued based on the circumference of the image carrier which is the length of the image carrier in the direction of rotation thereof or based on a detected reference position on the image carrier. A user can selectively switch, through operation of an operating section, between the issuing of the image writing reference position signal based on the circumference of the image carrier and the issuing of the image writing reference position signal based on the detected reference position.

Abstract: An image reading apparatus that, in a case where the light amount of light illuminated from an image reading lamp has decreased, maintains the quality of a read image without decreasing productivity, and a method for controlling that image reading apparatus, are provided. To accomplish this, this image reading apparatus is provided with RGB line sensors that read a color image, and a monochrome line sensor that reads a monochrome image and has a faster horizontal transfer speed than the RGB line sensors. Further, this image reading apparatus reads a monochrome image using the RGB line sensors even in a monochrome mode in a case where the light amount of the lamp for illuminating an original decreases and so an output level for reading an image with good quality cannot be obtained from the monochrome line sensor.

Abstract: Disclosed is an image forming apparatus whereby waiting time (downtime), which is required for forming an image by automatic adjustment relating to image formation density or image formation position, is made shorter than in the prior art. When an image having a size equal to or less than a prescribed size is formed is formed in this apparatus, the image to be formed is placed on an image carrier in such a manner that a vacant area for forming an adjustment pattern can be reserved on the image carrier. As a result, automatic adjustment relating to image formation density or image formation position can be executed while an image is formed.

Abstract: A technique for reducing downtime that accompanies the execution independently of adjustment processing for maintaining image quality and the execution of finishing processing relating to a printing medium. In order to apply the finishing processing to the printing medium in a finishing processing unit, an image forming apparatus to which this technique is applied sets a time between sheets that extends from end of image formation regarding a first sheet of the printing medium to start of image formation regarding a second sheet of the printing medium transported following the first sheet of the printing medium in the image forming unit, and executes adjustment processing, which is for maintaining image quality in the image forming unit, within the set time between sheets.
