摘要： A cleaning device includes first to third cleaning members that clean a surface of an endless belt that is looped over rollers including a driving roller. The first cleaning member is brought into contact with and separated from the surface at a predetermined timing. The second cleaning member is disposed upstream of the first cleaning member and downstream of the driving roller in a movement direction of the endless belt. The second cleaning member is in contact with the endless belt so as to prevent a tension variation of the endless belt caused by the first cleaning member from affecting the driving roller. The third cleaning member is disposed downstream of the first cleaning member. A contact state in which the third cleaning member is in contact with the endless belt is switched from a first contact state to a second contact state so as to reduce the tension variation.

摘要： An image processing apparatus includes an estimating unit and a hiding unit. The estimating unit extracts a subject specifying mark image corresponding to a specifying mark from a recording area image corresponding to a recording area in which an image is recorded, plural predetermined types of specifying marks having predetermined attributes different from an attribute of the image of the recording area and being used for specifying a region within the recording area by using different specifying methods, at least one of the plural predetermined types of specifying marks being recorded in the recording area. The estimating unit estimates the type of specifying mark corresponding to the extracted subject specifying mark image. The hiding unit hides the region specified by the type of specifying mark estimated by the estimating unit by using a hiding method which is uniquely determined for the estimated type of specifying mark.

摘要： An image processing apparatus includes following components. A blank-area identifying unit identifies a blank area having a size exceeding a predetermined size, from a non-specifying-mark image portion of a recording area image of a recording area that includes individual images and a specifying mark specifying an area containing images among the individual images. A concealing unit conceals a divided area specified by the specifying-mark image, among divided areas obtained by dividing a non-blank area by a gap having a width equal to or larger than a threshold in a specific direction, among gaps between the individual images arranged in the specific direction in the non-blank area. The non-blank area is an area of the non-specifying-mark image portion of the recording area image other than the blank area identified by the blank-area identifying unit.
