An image forming apparatus includes: plural image forming units that form images to be transferred to a recording medium; and a processor configured to cause an information display image to be transferred to a recording medium to which a diagnostic image that has been formed by a diagnosis target image forming unit, which is an image forming unit as a target for a diagnosis among the plural image forming units, is transferred, the information display image being an image representing information and having been formed by a different image forming unit.

Image forming apparatus and recording medium for diagnostic image and information display image

An image forming apparatus that forms an image on a recording medium includes: an image former that forms an image on a recording medium and is capable of forming an image for diagnosis, which is an image used for diagnosis of the image forming apparatus; an image reader that reads the image for diagnosis formed on a recording medium; and a processor configured to change at least one of a reading condition under which the image reader reads the image for diagnosis and a processing condition under which a read image obtained by the reading is processed in accordance with a mode of diagnosis of the image forming apparatus.

Image forming apparatus

An image forming apparatus that forms an image on a recording medium includes: an image forming unit that forms an image on a recording medium and is capable of forming an image for diagnosis, which is an image used for diagnosis of the image forming apparatus; and an adding unit that adds, to a recording medium on which the image for diagnosis has been formed by the image forming unit, information for control used to control output of a reading result from an apparatus used to read the recording medium, the reading result being obtained by reading the recording medium by the apparatus.

A light-emitting-device head includes a first light-emitting-device arrangement including light emitting devices arranged in lines extending in a first scanning direction; a second light-emitting-device arrangement including light emitting devices arranged in lines extending in a first scanning direction, the second light-emitting-device arrangement overlapping the first light-emitting-device arrangement in a second scanning direction at least in part; an optical device that forms an electrostatic latent image by focusing light emitted from the light emitting devices on a photoconductor and exposing the photoconductor to the light; and a switching unit that switches the light-emitting-device arrangement to be lit up between the first light-emitting-device arrangement and the second light-emitting-device arrangement at a switching position defined at any position in an overlapping portion where the first light-emitting-device arrangement and the second light-emitting-device arrangement overlap each other. The electrostatic latent image is composed of dots formed by a screening process performed with a screen having a predetermined screen angle. The switching unit defines the switching position such that when points in the electrostatic latent image that coincide with the switching position are connected to one another by a line, the line forms a zigzag shape while overlapping some of the dots, the zigzag shape including a line segment extending at the screen angle.
