Abstract: Adjustment image data is for use in adjusting imaging operation. The adjustment image data is stored in a storage of an image forming apparatus and read from the storage to form an image on a sheet of paper at the time of adjusting an imaging operation of the image forming apparatus. The adjustment image data includes a single identification mark located in the vicinity of a longitudinal center of the sheet of paper.

Abstract: An image recording medium includes two sheets made of resin and a toner image interposed between the two sheets. The toner image serves as an adhesive to bond the two sheets together and includes an information image. At least one of the two sheets includes a transparent portion to enable the information image to be visible through the at least one of the two sheets.

Abstract: An image forming method for an image forming apparatus having a fixing rotator and a pressure rotator opposite the fixing rotator includes transferring white toner and color toner onto a surface of a metallic sheet. The metallic sheet has a thermal conductivity of 0.34 W/m·K or less as measured by hot-wire method. The transferring process forms an unfixed color toner layer layered on an unfixed white toner layer on the metallic sheet. Further, the method includes conveying the metallic sheet, with the surface on which the white toner layer and the color toner layer being transferred facing the fixing rotator, between the fixing rotator heated and the pressure rotator to fix the white toner layer and the color toner layer onto the metallic sheet.

Abstract: A printing apparatus includes a printer and a sheet feeder. The sheet feeder feeds a sheet to the printer in a feed direction. The printer prints a folding guide line on the sheet with a transparent recording agent or a recording agent having a similar color close to the color of the sheet.

Abstract: A sheet bonding machine bonds together a first sheet and a second sheet including an adhesion layer formed on one side thereof, covered with a release paper, includes a transport unit to transport the first sheet unidirectionally, a feeder to feed the second sheet obliquely toward the first sheet, a separation unit, a reel, an adhesion point, and a tensioner. The release paper is removed from the second sheet by the separation unit located upstream from the contact portion, and reeled by the reel. The second sheet adheres to the first sheet via the adhesion layer 91b at the adhesion point located downstream from the separation unit. The tensioner is located upstream from the separation unit and keeps the second sheet taut.

Abstract: A mango kernel triturate or mango kernel extract has a bacteriostatic and antibacterial activity, and thus can be used in food products or cosmetics as a bacteriostatic and antibacterial agent. Furthermore, agents for preventing and treating acne or agents for preventing dental caries can be provided by adding said extract as an effective component.
