An image forming apparatus includes a correcting portion to correct gradation of inputted image data on the basis of a correction condition, an image forming device to form, on a recording material, a toner image corresponding to the corrected image data, a mounting portion, an executing portion to execute an output process for forming and outputting, on the recording material, a predetermined toner image for generating the correction condition, the predetermined toner image including a plurality of image regions different in density, an input portion to permit input of an execution instruction of the output process by an operator, and a controller to control notification of information to the operator. The controller provides notification prompting exchange of the fixing portions in certain cases.

A display control apparatus includes a display and a controller. The display displays a screen on which a target image and a processing image are arranged, the target image representing processing-target data, the processing image being an image for which a process to be performed on the processing-target data has been determined. The controller performs, in a case where an operation for moving the target image toward a position where the processing image is displayed has been received as a touch operation through the screen, control such that the processing image is moved toward a position where the target image is displayed.

A print control apparatus to communicate with a printing apparatus includes storage, display, setting, and selection units. The storage unit stores identification information of a plurality of sheets in association with stored adjustment values of a plurality of adjustment items. The display unit displays the stored identification information of the plurality of sheets. The setting unit sets, based on a user instruction, the adjustment values of the stored adjustment items. The selection unit selects, based on a user instruction, identification information of one sheet from among the identification information of the plurality of sheets displayed on the display unit. Based on a selection, the display unit displays, in addition to the displayed identification information of the plurality of sheets, at least one of the adjustment items of which set adjustment values are stored from among the adjustment values associated with the selected identification information of the one sheet.

An image forming apparatus has a power supply circuit including a power circuit, a main circuit, and a sub-circuit. The sub-circuit includes a timer that performs electrical conduction of a driving contact point of a heater by a first setting time and performs electrical conduction of a driving contact point of a discharge fan by a second setting time when a power switch is turned off. When it is determined that humidity in an image forming apparatus body detected by a humidity detection sensor is equal to or more than a threshold value, the first setting time is set to 0 and the second setting time is set to a predetermined time larger than 0. When it is determined that the humidity is less than the threshold value, the first setting time is set to a predetermined time larger than 0 and the second setting time is set to 0.

A toner cartridge supporting apparatus includes a storage portion, an insertion port, an opening/closing cover, a detecting portion for detecting a toner remaining amount, a control portion for controlling toner supply, a judging portion to judge whether or not a toner in a toner cartridge is exhausted, a message generating portion for generating a replacement message, a display portion for displaying the message, a toner cartridge replacement icon, and a toner cartridge moving portion, wherein a toner cartridge replacement message display function and a toner cartridge movement instruction function are provided as the control portion.

An information processing device includes a reception unit, a generation unit, and a display control unit. The reception unit receives, for a screen on which a first instruction part for issuing an instruction to execute a first process for which a set value for a setting item is set and a second instruction part for issuing an instruction to execute a second process for which a set value for a setting item is set are displayed, a synthesizing operation for synthesizing the first instruction part and the second instruction part. The generation unit integrates, by the received synthesizing operation, the first process regarding the first instruction part and the second process regarding the second instruction part to generate a specific process. The display control unit performs control such that a specific instruction part for issuing an instruction to execute the specific process is displayed on the screen.

A display control device includes a display section and a display controller. The display controller controls the display section so as to cause the display section to display a first image (703a to 703f) and a second image. The first image (703a to 703f) is displayed in an upper layer for the second image. The first image (703a to 703f) represents a category item. The second image represents a setting item belonging to the category item. The display controller controls the display section so as to cause the display section to display a predetermined image (705) in the first image (703a to 703f) according to the setting item that has been entered.

An identification apparatus includes a guide member defining a guide path, a scanning portion that scans the sheet inserted in the guide path, a first detection portion disposed upstream of the scanning portion in an insertion direction of the sheet in the guide path that detects presence/absence of the sheet, and a second detection portion disposed downstream of the scanning portion in the insertion direction in the guide path and detects presence/absence of the sheet. The identification apparatus is configured to start measurement of a surface property of the sheet by the scanning portion in response to a change in a detection result of one of the first detection portion or the second detection portion, and complete the measurement in response to a change in a detection result whichever of the first detection portion or the second detection portion not used in determining the start of the measurement.

An image forming system includes: a sheet feeder; an image former that forms an image on a paper sheet; a conveyor that conveys a paper sheet to a sheet ejection destination; a switcher that switches sheet ejection destinations; a reader that optically reads a paper sheet, and outputs a read image; an abnormal sheet detector that detects an abnormal paper sheet by analyzing the read image; a storage; a display; and a hardware processor that performs: ejection destination switch control to control the switcher to eject an abnormal paper sheet and a succeeding paper sheet to a second ejection destination different from a regular ejection destination; storage control, for each of the abnormal paper sheet and the succeeding paper sheet, to associate sheet information, the read image, and a stacking order with one another, and store them into the storage; and display control to cause the display to display them.

An image forming apparatus includes a transport unit, an image forming unit, an output tray, a toner container, and a processor that realizes a function of a conformity decision unit, a change reception unit, and a controller. The controller discharges, when the conformity decision unit decides that the toner container is not a conforming product, a quality check sheet to the output tray each time a predetermined number of sheets have been printed, or each time a predetermined time has elapsed. The change reception unit receives a change of a quality adjustment value from a user. The controller controls the operation of the transport unit and the image forming unit, according to the quality adjustment value that has been changed and received by the change reception unit.
