The invention provides an apparatus-information indicator, a label sheet, an electronic apparatus and an image forming device. The apparatus-information indicator includes an indication surface, an underlying segment formed on the indication surface by a first dot pattern, and a character area formed on the underlying segment by a second dot pattern different from the first dot pattern to indicate given apparatus information. Respective colors of the underlying segment and the character area are substantially equal in hue, and substantially different in lightness. Thereby, when an apparatus displays the apparatus type name, specification, discard method and other information, the cost is prevented from increasing, the incensement of the production process is inhibited, and the apparatus information can be recognized easily.
