    摘要： An image forming apparatus includes a movable intermediary transfer member (40), a toner image forming unit (PY, PM, PC, PK), a rotatable transfer member (12), a fixing unit (60), a recording material feeding portion (31), an executing portion (34), and first and second cleaning units (90). The first cleaning unit (91) includes a first brush roller (91B), a first rotatable member (91C) and a first blade member (91D). The second cleaning unit includes a second brush roller (92B), a second rotatable member (92C), a second blade member (92D) and a third blade member (92F). The third blade member is disposed downstream of the cleaning portion and upstream of a contact portion, between the second rotatable member and the second brush roller, with respect to a rotational direction of the second rotatable member, and scrapes a deposited matter off the second rotatable member with the rotation of the second rotatable member (92c).

    摘要： A printing system includes: a printing unit that performs printing on a sheet; a conveyance mechanism that has a printing path for guiding a sheet to a printing position of the printing unit and a reverse path for reversing the sheet passing through the printing position and guiding the sheet again to the printing position; a control unit that performs double-side printing processing depending on a plurality of methods in which maximum numbers of the sheets existing in the conveyance mechanism at the same time are different from each other; and a determination unit that determines a probability of sheet jamming occurring in the conveyance mechanism. When the determination unit determines that the jamming occurrence probability is high, the control unit selects the method in which the maximum sheet number is small, and performs the double-side printing processing in accordance with the selected method.

    摘要： An image forming apparatus (300) connected to a conveying-speed-changeable sheet post processing device (350) includes a discharging unit which discharges a sheet in a reverse discharge mode with front and back surfaces of the image-formed sheet reversed, and a non-reverse discharge mode without front and back surfaces of the image-formed sheet reversed, and discharges the sheet to the device (350) at a first speed or a second speed lower than the first speed; and a control unit which controls the discharging unit to discharge the sheet at the first speed in the reverse discharge mode, and discharge the sheet at the second speed in the non-reverse discharge mode. When a previous sheet is discharged at one of the first speed and the second speed, the control unit controls the discharging unit to discharge a next sheet at the same speed as the previous sheet, regardless of which mode the next sheet is to be discharged in.

    摘要： In a related-art sheet detecting device including a flag rotating while being in contact with the leading edge of a sheet, it is difficult to improve productivity related to sheet conveyance by increasing a sheet conveying speed or reducing the interval between sheets successively conveyed.
    A sheet detecting device includes a sensor flag member 23 that is pressed and rotated by the leading edge of a conveyed sheet. The sensor flag member 23 is on standby in a standby position where the leading edge of the conveyed sheet abuts an abutment surface of the sensor flag member 23. An optical sensor 24 detects the conveyed sheet on the basis of a posture of the sensor flag member 23 pressed by the leading edge of the conveyed sheet. The sensor flag member 23 is rotatable to a sheet passage posture where the sheet is allowed to pass. After the trailing edge of the conveyed sheet passes the sensor flag member 23, the sensor flag member 23 is rotated from the sheet passage posture in the same direction as a sheet conveying direction and is positioned in the standby position.

    摘要： An image forming apparatus (1) includes an apparatus body (1A), an image forming unit (2), and a retransporting unit (20). The retransporting unit (20) includes a transporting roller (21) for applying a transporting force to the sheet and an input portion (22) disposed at a position shifted upstream of the transporting roller (21) in a retransporting direction. The input portion (22) is configured to receive an input of a drive force supplied from the apparatus body (1A). The retransporting unit (20) further includes a drive shaft (23) extending in a retransporting direction. The drive shaft (23) is configured to transmit the drive force from the input portion (22) toward the transporting roller (21) by rotating about an axis thereof. A height of the image forming apparatus may be reduced by this configuration.

    摘要： An improved architecture for use in a tightly integrated serial or parallel printer includes an inverter module (30) that comprises a straight pass-through media path, as well as, an invert path. This auxiliary 'pass-through' media path of the inverter allows a sheet to enter the inverter 'backwards' through the traditional duplex exit path and continue straight out the inverter into the media path of a downstream engine to receive an image thereon.
