    Abstract: An image forming apparatus includes an image forming portion, an image reading portion, and a test processing portion. The image forming portion forms an image on a sheet using a plurality of recording elements. The image reading portion reads the image on the sheet. The test processing portion causes the image forming portion to form a test image in a marginal region of the sheet, and causes the image reading portion to read the test image. The test processing portion is capable of executing a divisional test in which only some of the plurality of recording elements are used for forming a single test image to be formed on a single sheet and all of the plurality of recording elements are used for forming a test image group constituted of a plurality of the test images to be formed on a plurality of the sheets.

    Abstract: An image reading device includes a first image reading portion, a cooling portion, a second image reading portion, and a notification processing portion. The first image reading portion reads an image of a document sheet at a first reading position. The cooling portion cools the document sheet at a cooling position downstream in a feeding direction of the document sheet with respect to the first reading position. The second image reading portion reads an image of the document sheet at a second reading position downstream in the feeding direction with respect to the cooling position. In a case where a difference image different from a first image read by the first image reading portion, the difference image being included in a second image read by the second image reading portion has been detected, the notification processing portion provides a notification that the difference image has been detected.

    Abstract: An image forming system includes a plurality of processing apparatuses. An image forming apparatus includes an image forming section, storage, an acquiring section, a first specifying section, a receiver, a second specifying section, and a notifying section. The storage stores therein a position of each of the processing apparatuses. The acquiring section acquires state information from each of the processing apparatuses. The state information indicates whether a corresponding one of the processing apparatuses is in a normal function state or a malfunction state. The first specifying section specifies, from among the processing apparatuses, a malfunctioning processing apparatus for which the malfunction state is indicated by the state information. The second specifying section specifies a relative position of the malfunctioning processing apparatus with respect to a mobile terminal device. The notifying section notifies of specific information relating to the relative position specified by the second specifying section.
