A display device usable with an image forming apparatus includes a liquid crystal unit including a liquid crystal screen and a frame supporting the liquid crystal screen; a supporting member of metal supporting the liquid crystal unit; and an insulative spacer providing a space between the frame and the supporting member at a position of the frame corresponding to an outside area of a display area of the liquid crystal screen.

The present invention provides an image forming apparatus comprising: at least one first module and at least one second module configured to execute functions corresponding respectively to the at least one first module; a first control unit configured to notify, to a corresponding second module, a request accepted by the at least one first module; and a second control unit configured to control in accordance with the notification from the first control unit, the corresponding second module, wherein the at least one first module is activated at all times from when the image forming apparatus is activated, and the at least one second module is generated as a container of an execution environment that is independent of an operating system and whose activation state is controlled by an instruction from the second control unit.

The image reading unit (2) reads an image from a document. The image forming unit (3) is located below the image reading unit (2) and forms an image on a sheet. The operation unit (5) is rotatably supported at a position forward of the image reading unit (2) and receives user's operation. The post-process unit (7) is provided between the image reading unit (2) and the image forming unit (3), and has, at a position interfering with the rotation range of the operation unit (5), a retracted portion (772) retracted rearward in the post-process unit (7). The post-process unit (7) performs a post-process on a sheet on which an image has been formed by the image forming unit (3).

The operation unit (5) is configured to receive user's operation and supported at a position frontward of the image reading unit (2) by the support housing (10) so as to be rotatable within a predetermined rotation range around a rotation shaft parallel to a right-left direction of the image formation apparatus (100). The information reading unit (6) is configured to read information about the user and housed in the housing side surface (12) so that a part of the information reading unit (6) is present rearward of the operation unit (5) in a first attitude in which a surface of the operation unit (5) is closest to a vertical plane, and a part of the information reading unit (6) is present downward of the operation unit (5) in a second attitude in which the surface of the operation unit (5) is closest to a horizontal plane.

An image processing apparatus includes: a controller configured to: control a reader to read an image on a reading medium; determine whether a preview image corresponding to the read image is to be displayed on a display, based on a setting value for a setting item, reading-obtained information, or the setting value and the reading-obtained information, in a case where the controller determines that the preview image is to be displayed, control the display to display the preview image, and execute a particular processing based on obtained read-image data in a case where a processing instruction is input after the preview image is displayed; and in a case where the controller determines that the preview image is not to be displayed, execute the particular processing based on the read-image data without displaying the preview image.

An image forming apparatus forming an image on a sheet, including: an exterior member movable with respect to an apparatus main body; a locking portion locking the exterior member to the apparatus main body such that the exterior member is not moved with respect to the apparatus main body; a display portion which is disposed on the exterior member and displays a state of the locking portion; and a light source turning on the display portion, in which the display portion includes a thin portion which is a part of the exterior member, has a thickness less than thicknesses of other portions of the exterior member, and transmits light from the light source.

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 an image forming unit configured to form an image on a sheet based on a mode selected from a plurality of modes having different image forming speeds; a memory configured to store first data for a first mode included in the plurality of modes, the first data indicating a correspondence for the first mode between a type of the sheet and the image forming speed, and second data for a second mode included in the plurality of modes, the second data indicating a correspondence for the second mode between a type of the sheet and the image forming speed; a display; and a controller configured to: determine a first image forming speed for the first mode from the first data based on the type of the sheet; and determine a second image forming speed for the second mode from the second data.

There are a paper storage that stores paper on which an image is formed, a paper guide that is movably provided in the paper storage and restricts a position of the stored paper, a paper size acquirer that acquires a size of the paper stored in the paper storage, a size change determiner that determines, by using the acquired size of the paper, whether the paper stored in the paper storage was changed, a confirmation information selector that, when it is determined that the paper stored in the paper storage was changed, selects confirmation information requesting confirmation of a position of the paper guide in the paper storage in accordance with a difference in size between paper before and after the change, and a confirmation information notifier that notifies the selected confirmation information.

An image forming apparatus includes an exposure unit provided with a rotatable polygon mirror including a plurality of reflecting surfaces for scanning a light beam emitted from a light source to expose a photosensitive member with the light beam according to image information. A determining unit determines an end of lifetime of the exposure unit based on a detecting result of density of a toner image detected by two detecting units at a first timing and a detecting result of density of the toner image detected by the two detecting units at a second timing after the first timing.
