An image processing device includes a color extractor, an area cutout unit, a receiver, and a sticky image cutout unit. The color extractor extracts, from image information that includes multiple sticky notes, pixels of a color used for the sticky notes. The area cutout unit cuts out an area that is a set of pixels extracted by the color extractor. The receiver receives input of a dividing line with respect to an area to be cut out by the area cutout unit. The sticky image cutout unit splits an area cut out by the area extractor along a dividing line received by the receiver, and cuts out an area having a surface area within a predetermined range from among the split area as a sticky image.
