An image forming system includes a recording processing portion, an acquirement processing portion, and an output processing portion. The recording processing portion records a consumed amount of a consumable consumed by an image forming apparatus per predetermined unit time. The acquirement processing portion acquires prediction data that indicates a predicted consumed amount of the consumable per the unit time for a time period from a predetermined standard time, based on a comparison result between: a first record result corresponding to a first time period extending to a reference time; and a second record result corresponding to a predetermined second time period extending to the standard time, among a record result recorded by the recording processing portion, the reference time being a predetermined specific time period earlier than the standard time. The output processing portion outputs the prediction data acquired by the acquirement processing portion.

An image scanning unit optically scans an image of a predetermined scanning area that includes a platen glass on which a document is put. A document cover is capable of rotation and covers the platen glass. A first movable member moves in a direction substantially perpendicular to the platen glass in accordance with opening and closing of the document cover. A second movable member moves in a direction substantially parallel to the platen glass in accordance with movement of the first movable member when the first movable member contacts. A cover status detecting unit obtains the image from the image scanning unit and detects a status of the document cover on the basis of an image of the second movable member in the scanning area.

An image processing device includes a modulation clock generator, a line synchronization signal generator, a line image sensor, and an image processor. The modulation clock generator is configured to generate the modulation clock by modulating a frequency of a reference clock at a predetermined modulation cycle. The line synchronization signal generator is configured to generate, on the basis of the modulation clock, a line synchronization signal whose line cycle varies from line to line. The line image sensor is configured to sequentially read an image of one line of a document at a timing corresponding to the line synchronization signal and to output image data. The image processor is configured to process the image data on the basis of the modulation clock.
