An image forming apparatus includes: an image processor configured to perform image processing to image data based on a conversion condition to output converted image data; an image forming unit configured to form an image based on the converted image data output from the image processor, the image forming unit being controlled based on an image forming condition; a controller configured to perform tone correction control, density evenness control, and total density control that is combined the tone correction control and the density evenness control, wherein, in the tone correction control, the controller operates as follows: control the image forming unit to form a first test image on a sheet; obtain first reading data related to the first test image on the sheet.

An image forming apparatus comprising: an image forming unit configured to form an image on a recording medium based on an image forming condition; an image reader configured to read an image for adjustment of the image forming condition, which is formed on the recording medium; and a controller configured to: control the image forming unit to form images for adjustment; control the image reader to read the images for adjustment; determine a target data based on a reading result of a first image included in reading results of the images for adjustment; and adjust the image forming condition, during execution of a job in which the image forming unit forms a plurality of images on a plurality of recording mediums, based on the target data and a reading result of second image included in the reading results of the images for adjustment.

A method for display control is provided. The method includes obtaining information of a remaining amount display color displaying a remaining amount of a consumable supply, obtaining the information of a background color in a displaying area displaying the remaining amount of the consumable supply, and changing a display content in the displaying area on the basis of the remaining amount display color and the background color.

When sheets having the same surface property and grammage are registered on a size basis, adjustment value registration operations need to be repeated for the respective sheets as many as these sizes. An image forming apparatus that includes a display unit and forms an image on a sheet sets a setting value of adjustment influenced by the characteristics of the image forming apparatus upon forming an image by using a sheet, and then displays a sheet list which displays a list of a plurality of types of sheets on a display unit and reflects the set setting value on at least one sheet selected from the sheet list.

There is provided an image forming system including at least a first image forming apparatus that includes a first image forming unit and an obtaining unit configured to obtain operation-related information related to an operation of the first image forming unit. The image forming system further includes a carryover unit configured to carry over, to a second image forming apparatus, information related to an operation of a second image forming unit of the second image forming apparatus among the operation-related information obtained by the first image forming apparatus when the second image forming apparatus is newly used in the image forming system. The operation-related information includes operation history information of the first image forming unit.

An information processing apparatus includes at least one processor configured to: acquire physical-property-value information of a recording medium; using information regarding a printing machine, perform an evaluation as to whether there is a possibility that the recording medium causes trouble for printing by the printing machine, the evaluation being performed with respect to at least one printing performance indicator based on the physical-property-value information; and output a result of the evaluation to a display device.

An image forming device includes a printer, a display, and a controller. The printer forms a desired image indicated by image data on a sheet. The display displays the desired image. The controller receives a first designation, by a user, of a designation region of the desired image displayed on the display. The controller receives a second designation, by the user, of a superimposition position at which an abnormality region containing an abnormality is superimposed on the desired image. The controller transmits user designation information indicating the designation region and the superimposition position to an external device.

A control device includes a memory configured to store variable data including a plurality of page images each including a variable region where an image is variable for each page and a non-variable region including the same image irrespective of the page and a display processing section configured to cause a display device to display a printing preview screen for the variable data. The display processing section causes the display device to display the printing preview screen that displays one or a plurality of row images in which the plurality of page images are arranged in a row in a first direction corresponding to the width direction of a printing medium.

A display unit of the present invention displays icons respectively for a series of process steps of a pretreatment unit and an analysis device on a setting screen. The display unit displays a first shutdown icon for a first shutdown step and a second shutdown icon for a second shutdown step in association with the icons respectively for the series of process steps, the first shutdown step being performed when the pretreatment unit and the analysis device end process steps without causing an error, the second shutdown step being performed when the pretreatment unit and the analysis device end the process steps as an error is caused while the process steps are performed. When a user selects any one of these icons, the display unit displays an input screen on the setting screen for inputting the setting information for the process step corresponding to the selected icon.

An image forming apparatus includes an image forming portion, a belt, a plurality of stretching rollers including an inner roller and an upstream roller, an outer member, an urging member, a first position changing mechanism, a storing portion, a controller, and an operating portion. The controller controls the first position changing mechanism on the basis of a kind of a recording material on which an image is formed, first set information stored in the storing portion, and first input information for changing setting of a position of the urging member inputted to the controller through the operating portion.
