  • SHEET MOISTURIZING APPARATUS AND IMAGE FORMING SYSTEM
    Publication number: 20150370211
    Abstract: A sheet moisturizing apparatus includes a moisturizing section, a water feeding section and a control section. The moisturizing section includes a pair of moisturizing rollers that moisturizes a sheet and a driver that rotates the pair of moisturizing rollers. The water feeding section feeds water to an outer peripheral surface of the pair of moisturizing rollers. The control section controls the water feeding section to feed water only to a predetermined part of the outer peripheral surface of at least one of the pair of moisturizing rollers, and thereafter allows the rotating pair of moisturizing rollers to pinch the sheet so as to bring the predetermined part into contact with a sheet finishing area of the sheet.

  • Image forming apparatus and method
    Patent number: 6636251
    Abstract: An image forming and apparatus is provided in which a halftone density of an image is stabilized irrespective of a timing at which writing on scanning lines is started, even when using multiple laser beams. First, it is determined whether or not a portion exposed by adjacent laser beams (i.e., exposed by both of two beams simultaneously) is present. If the result of the determination is affirmative, it is then determined whether or not a portion adjacent to the exposed portion and not exposed by a laser beam is present. If the result of this determination is affirmative, exposure by fine dots is added to the portion not exposed by a laser beam.
