Abstract: An image forming apparatus that forms an image on a front side of a sheet then reverses the sheet front and back sides and forms an image on the back side, including: a sheet conveying path; a sheet edge portion detection sensor; a sheet reference mark detection sensor; a first determination section for determination of a position of an image to be formed on the back side, referring to a detected edge of the sheet; a second determination section for determination of a position of an image to be formed on the back side, referring to a detected reference mark; and switching section for switching whether to use the first determination section or the second determination section for determination of the position of the image to be formed on the back side of the sheet, based on setting information on double-sided printing to be performed by the image forming apparatus.

Abstract: Disclosed is an image forming apparatus which combines a character string image with an image of image data and forms a combined image, including: a display section to display the character string image; and a control section to generate the character string image to be combined to the image and to display the character string image on the display section, wherein the control section controls the display section to display the character string generated with same font data as font data used for forming the character string image of the combined image on a sheet.

Abstract: An image forming apparatus includes: an image forming unit for forming an image based on an input image data on a recording medium on which a first image is previously formed; a storage unit for storing an image data relating to the first image; a first reading unit for reading a second image on the recording medium after the image is formed on the recording medium by the image forming unit; and a control unit for comparing an image data obtained by superposing the input image data on the image data relating to the first image with an image data relating the second image read by the first reading unit to detect a misprint in the image forming unit.

Abstract: Disclosed an image forming apparatus which has a plurality of functions, including: a display section to display operation screens corresponding to the respective plurality of functions; an operation section; a function group storage section to store a function group consisting of a plurality of functions related to one another among the plurality of functions; and a control section to display on the operation screen, when an operation screen corresponding to one function in the function group stored in the function group storage section is displayed, that the image forming apparatus has the remaining function in the function group.

Abstract: An image forming apparatus that forms an image on a front side of a sheet then reverses the sheet front and back sides and forms an image on the backside, including: a sheet conveying path; a sheet edge portion detection sensor; a sheet reference mark detection sensor; a first determination section for determination of a position of an image to be formed on the back side, referring to a detected edge of the sheet; a second determination section for determination of a position of an image to be formed on the back side, referring to a detected reference mark; and switching section for switching whether to use the first determination section or the second determination section for determination of the position of the image to be formed on the back side of the sheet, based on setting information on double-sided printing to be performed by the image forming apparatus.

Abstract: Disclosed is an image forming apparatus including an image reading section to read image from a document; a display section to display a reduced image of the image read by the image reading section; an image output section to output the image read by the image reading section on a transfer paper; and a control section to make the display section display at least a part of a sequential operation which starts from image reading and ends in image output, by a moving image that uses the reduced image.

Abstract: An image reading apparatus including: an image reading section for reading a document to obtain a document image; and a control section for adding an additional image to a document image corresponding to one page in the document image obtained by the image reading section under a dual page mode to generate image information of the document image added with the additional image, wherein the control section adds the additional image to the document image corresponding to one page away from a binding margin region.

Abstract: An image forming apparatus including: an image forming section for forming images on both surfaces of a recording medium; and a control section for controlling the image forming section to form, on each surface of the recording medium, a first image and image each including a test chart image for detecting a deviation between image formation areas on both surfaces of the recording medium; wherein at least one of the image and the second image includes an identification image for identifying a reference surface and the other surface the recording medium.

Abstract: Disclosed is an image forming apparatus comprising: a door for allowing a user to access to a sheet path of the image forming apparatus to recover from a sheet jam; a lock for locking the door; an input unit for inputting information about a user; and a controller for controlling the lock to unlock the door in a case where the information about the user is recognized.

Abstract: An image forming apparatus for forming an image according to attribute information of a print job, the image forming apparatus being connected to a remote apparatus and including: a memory section for memorizing the attribute information for each print job; an operation section through which an editing operation is capable for the attribute information; and a control section configured to enable editing operations for the attribute information memorized in the memory section through the operation section and through the remote apparatus, and to control the editing operation through the operation section and the editing operation through the remote apparatus for the attribute information of one and the same print job.

Abstract: An image forming apparatus connected to a network, including: an operation section for editing a first job ticket specifying an output condition to output image data onto an output medium; an interface section to communicate a remote operation apparatus through the network; and a control section to allow the remote operation apparatus to edit a second job ticket.
