A display control method for an image forming apparatus includes detecting that a document is placed on a document reading unit, determining, when it is detected that the document is placed on the document reading unit, whether the size of the document is a predetermined size, displaying a first function screen on a display when a first function capable of performing one of a plurality of functions accompanying a reading operation for a document placed on the document reading unit is performed, and displaying a second function screen to which a screen is switched from the first function screen and that is displayed when a second function created by modifying the first function based on a specific setting is performed, in a case where, while the first function screen is displayed, it is determined that the size of the detected document is not the predetermined size.

First correction data for use in a first printing mode is generated by image density measurement in the first printing mode, and second correction data for use in a second printing mode, which is different from the first printing mode in peripheral speed ratio of a developing roller to a photosensitive drum, is generated by image density measurement in the second printing mode. First processing for generating first and second correction data for the first and second printing modes, respectively, by density measurement, or second processing for generating the first correction data by density measurement and generating the second correction data using the generated first correction data and a difference in image density between the first printing mode and the second printing mode is executed. The first processing is executed when a predetermined condition is satisfied.

An application operating on a first apparatus transmits a change request to a second apparatus in response to a user's operation on the application, and a browser operating on the first apparatus periodically transmits an update request for a screen displayed in the browser to the second apparatus. If an update request received from the first apparatus that is the same as a transmission source of the change request is an update request received for the first time since the change request is received from the first apparatus, the second apparatus transmits a screen corresponding to the change request to the first apparatus as a response to the update request.

An image forming apparatus acquires a remaining amount of a consumable part that is detachably mounted to the image forming apparatus and is used for image forming. The apparatus predicts a remaining number of days, which is a number of days remaining in which the consumable part can be used, based on a change of the acquired remaining amount, and notifies a server apparatus, which performs processing for delivering a consumable part to be used for replacement of the consumable part, of the acquired remaining amount and the predicted remaining number of days.

An image forming apparatus includes a document reader, a storage for storing image data, an image output unit and a control unit. The control unit includes: a function setup controller for setting up the image output conditions of output images; and a control-unit side controller having a function of displaying a function setup screen corresponding to the function setup controller, on a display panel. The function setup controller has an additional input mode having a function of reading documents a multiple number of times to form multiple sheaves of documents. The additional input mode includes: an individual setup function of setting up individual image output conditions for each sheaf of documents and an all-in setup function of setting up identical image output conditions for all sheaves of documents. When the additional input mode is set up, the control unit-side controller offers a display of a setup change suggestion of the image output conditions for the next input on the display screen at the stage where the first image data input has been completed.

An image forming apparatus including: an image forming unit; a replenishment mechanism; and a controller configured to control the replenishment mechanism, the controller controls, after a container that fails to satisfy a predetermined condition relating to a remaining amount of the developer is removed from an attaching portion, the image forming unit based on a mode of prohibiting an image from being formed based on a print job in a case where another container different from the removed container is attached to the attaching portion, and controls, after the container is removed from the attaching portion, a display to display a first screen for prompting reattachment of the container in the case where the another container is attached to the attaching portion, the first screen including a button that allows the mode to be canceled.

An image forming apparatus includes the following. An image carrier forms an electrostatic latent image by exposure. A developing apparatus stores a developing agent including toner and which develops the image carrier. A collector collects in the developing apparatus the developing agent scattered from the developing apparatus. An input unit is used by a user to select a screen type relating to a fineness of a halftone image. An adjuster is able to change strength of an electric field between the collector and the image carrier. A hardware processor which controls the adjuster to change the strength of the electric field according to the selected screen type.

A sheet management system includes an image forming apparatus and first and second information processing apparatuses to communicate with the image forming apparatus. The first information processing apparatus includes a first LAN interface connected to the image forming apparatus, a second LAN interface connected to a network, and a first display to display information. To display a screen for performing sheet management on the first display, the first information processing apparatus obtains device information of the image forming apparatus based on information on an apparatus connected via the first LAN interface. The second information processing apparatus includes a third. LAN interface connected to the network and a second display to display information. To display a screen for performing sheet management on the second display, the second information processing apparatus obtains device information of the image forming apparatus via the third LAN interface using address information entered by a user.

A display control device displays a user interface enabling selecting one of N (where N is an integer of 3 or more) selection options, and includes: an extractor configured to extract M (where M is an integer of 2 or more and less than N) selection options including a currently selected selection option from among N selection options; and a display controller configured to display a first screen including the M extracted selection options selectably at positions corresponding to an order of preference, and not selectably including remaining selection options.

An operation console used in relation to an apparatus as an object of control operated by a user operation includes: a display device having a display area for displaying information to the user; an input device for the user to input a request; and a display control device displaying, if a request for displaying specific information on said display device is input through the input device, the specific information on the display device. The input device includes a plurality of operation buttons for inputting a plurality of requests, corresponding to respective requests, arranged in the vicinity of the display area. Among the plurality of operation buttons, an operation button corresponding to the request for displaying the specific information is provided closest to the display device.
