    摘要: A sheet conveying device includes a first rotating shaft (601), a driving roller (602) fixed to the first rotating shaft (601), a driven roller (604) that faces and is pressed against the driving roller (602), and a second rotating shaft (603) supporting the driven roller (604). The driving roller (602) or the driven roller (604) includes a cylindrical center portion, and end portions (608) located at both ends of the center portion and having an approximately circular truncated cone shape. Surfaces of the center portion and the end portions (608) are made of an elastic material. An outer surface of the center portion is matched with outer surfaces of one end of the end portions (608), and a diameter of another end of the end portions (608) is larger than a diameter of the one end. The end portions (608) have a hollow (609) inside, and have a thin surface.

    摘要: A sheet processing apparatus (2) includes: a folding unit (215, 230) that folds a sheet bundle (SB); a pressing unit (260) that presses a fold part of the sheet bundle (SB), which has been folded by the folding unit (215, 230), in a thickness direction of the sheet bundle (SB) to enhance folding of the fold part; and a moving unit (263) that advances and returns the pressing unit (260) in a width direction of the sheet bundle (SB). The pressing unit (260) starts pressing from a predetermined position in the width direction of the sheet bundle (SB) during advancing movement, and releases pressing after going past one end of the sheet bundle (SB). The pressing unit (260) starts pressing from the predetermined position during return movement and goes past the other end of the sheet bundle (SB).

    摘要: An image forming apparatus includes at least first (202K), second (202C) and third image (202M) carriers (202M), a first drive source (98), a second drive source (99), at least one visible image forming mechanism for forming a visible image on the image carriers, a transfer unit (15) for overlappingly transferring the visible images, an image detector (136), and a controller (150). The first drive (98) source transmits a driving force to at least the first image carrier (202K). The second drive source (99) transmits a driving force to at least two image carriers other than the first image carrier (202K). The controller (150) calculates an amount of misalignment of the overlapped visible images that remain at the start timing of image formation based on the start timing of image formation after the timing correction, and separately determines driving speeds of the first (98) and the second drive sources (99) based on the amount of misalignment of the overlapped visible images.
