Abstract: An image forming apparatus indicates on a display a message prompting placement of paper, which is to be placed in a cassette, on a reading device and issuance of an instruction to start reading, in order to set a size of paper placed in the cassette. When touch of a button is detected after the message is indicated and a user operation giving an instruction to start reading is accepted, the image forming apparatus detects the size of placed paper using the reading device. The image forming apparatus then sets the size of paper placed in the cassette to the detected size.

Abstract: This invention is related to a method of manufacturing a tea drink, which comprises the steps of subjecting tea leaves to extraction to obtain an tea extract and adjusting the pH of the tea extract to the range of 5.0-6.0, mixing nitrogen into the tea extract while applying a negative pressure of 0.01 MPa or more, stabilizing the tea extract in succession to the step of applying a negative pressure by maintaining the tea extract under a pressure of not higher than atmospheric pressure for a period of 30 seconds to 20 minutes, and adjusting the pH of the tea extract to the range of 5.5-6.5 during or subsequent to the step of stabilizing the tea extract.

Abstract: The recording sheet supporting surface of the transport belt comes in contact with the photosensitive drums for cyan, magenta, yellow, and black in the color copy mode, and is separated from the photosensitive drums aside from the photosensitive drum used for forming a black image in the monochrome copy mode with the image forming units for cyan, magenta, and yellow not being activated. With this separating operation, the distance on the transportation path of the recording sheet measured from the synchronizing roller to the transfer position of the photosensitive drum used for forming a black image in the monochrome copy mode is longer than in the color copy mode. Thus, the start time of scanning the surface of the photosensitive drum used for forming the black image is delayed in the monochrome mode according to the difference in distances between the color and monochrome modes.

Abstract: An image forming apparatus is provided with a plurality of image forming units along a transportation path of a recording sheet transported by a revolving transport belt, each image forming unit including an image holding component. The image forming apparatus is further provided with a transport belt moving unit for moving the transport belt between a first state and a second state by changing a form of a revolution of the transport belt, the first state being where the transport belt does not touch at least one of the image holding components and the second state being where the transport belt touches the image holding components not touched in the first state.

Abstract: A belt drive used in image forming apparatuses which minimizes the transverse movement of the belt across the length of a roller and prevents the riding up of the belt onto the roller. The belt drive device has a belt equipped with elastic guide members mounted on each edge or on the back surface of the belt near each edge. The belt is suspended over two or more rollers and driven by the drive belt. At least one of the rollers is a drive roller having a rotating member mounted between the elastic guide member and the roller end area such that the rotating members rotate independently of the roller.
