Abstract: An image forming apparatus has an image forming section for forming an image in a plurality of operational modes and a display device for executing display in a plurality of colors. Color information corresponding to the plurality of operational modes is stored in a memory. A CPU reads color information corresponding to an operational mode to be executed from the memory and controls the color to be displayed on the display device.

Abstract: An image forming apparatus provided with a function for binding a set of recording sheets by interposing said set of recording sheets between a folded cover sheet. When cover mode is set, the cover sheet is transported in a folding unit. The folding unit is controlled so as to fold said cover sheet into three sections of a front cover, spine and back cover. Content copy sheets are inserted in the folded cover sheet. The image forming apparatus is capable of cleanly binding documents even when the set of recording sheets is thick because the cover sheet can be folded in three.

Abstract: In a centrifugal separating method using connected tube assemblies in which a plurality of tubes are connected to each other, the connected tube assemblies that have been used in a previous process are mounted in a centrifugal machine as they have been to perform centrifugal separation, and are used as they are in a subsequent process. In a centrifugal machine, the rotor is formed with a plurality of holes arranged in straight line, each of the holes receiving and supporting one of a plurality of tubes of the connected tube assembly Alternatively, the rotor is formed with a straight or arc-shaped long hole for receiving and supporting two or more tubes of a plurality of tubes of the connected tube assembly.
