摘要： A development device includes a developer supply member that supplies a developer supporting member with liquid developer from a developer container. An agitating member is disposed in the developer container supplies the developer supply member with the liquid developer. The developer container includes a partition member partitioning between and extending above first and second developer holding sections. The partition member is aligned in parallel to an axial direction of rotation of the agitating member and allows liquid developer to move between the first and second developer holding sections.

摘要： An image forming apparatus includes an image forming portion that superposes images on an intermediate transfer member by rotations of the intermediate transfer member to form a color image on the intermediate transfer member, a transfer portion that transfers the image formed on the intermediate transfer member in the image forming portion to a sheet, a fixing portion that fixes the image onto the sheet, and a switchback portion that switches back the sheet so as to return the sheet to the transfer portion for forming the image on a second face of the sheet, after the image has been formed on a first face of the sheet. The sheet is returned through a return path at a return speed equal to or lower than a delivery speed of the sheet in the transfer portion, when the image for the second face of the sheet is the color image.

摘要： A fuser allows a sheet medium on which a toner image has formed to path through while heating the sheet medium, thereby fusing the toner image on the sheet medium. A plurality of first rollers are arrayed in a first direction. A plurality of second rollers are arrayed in the first direction and respectively coming in contact with the first rollers with a first pressure. The second rollers are adapted to eject the sheet medium nipped between the first rollers and the second rollers to the outside of the apparatus in a second direction perpendicular to the first direction. A plurality of third rollers are arrayed in the first direction so that each of the third rollers is disposed between adjacent ones of the first rollers, the third roller adapted to be brought into contact with the sheet medium with a second pressure which is smaller than the first pressure.

摘要： An automatic document feeder for sending a document from a document setting position on a document bearing plate to a document feeding path and returning the document onto the document bearing plate after feeding of the document along the document feeding path. A document mover includes a moving plate for moving the document that has been returned to the document bearing plate to the document setting position. A document presser presses the document that has been moved by the document mover to the document setting position. A controller controls the operation of the document presser and the document mover. The controller operates the moving plate of the document mover to move the document that has been returned to the document bearing plate to the document setting position, then operates the document presser to press the document that has been moved to the document setting position, and causes the moving plate of the document mover to recede, while maintaining the document in a pressed state.

摘要： An automatic document feeder conveys an original along a conveying path to an original reading section in an image processor. First and second registration rollers for abutting the conveyed original against their contact portions, and a guide plate for guiding the conveyance of the original to the registration rollers are arranged in the conveying path. The first registration roller includes a plurality of reversing rollers made of rubber for reversing the original along a reversing path, and the reversing rollers are arranged a predetermined distance away from each other along an axis of their supporting shaft. A side edge in the direction of conveyance of the guide plate is in such a comb shape that projections and non-projections are alternatively formed. Each of the projections is opposite to a region between the adjacent reversing rollers, and extends toward the downstream side of the contact portions in the direction of conveyance. Each of the non-projections is opposite to each of the reversing rollers, and is positioned on the upstream side of the contact portions in the direction of conveyance and is in close proximity to the contact portions.

摘要： A document conveying apparatus has a document pushing-down/adjusting mechanism disposed at an upper position on the downstream side of a document discharge port. The document pushing-down/adjusting mechanism acts on the rear end of the document on delivery after its rear end is substantially liberated from being nipped by a pair of document discharge rollers, forcibly pushes the rear end of the document down toward the upstream end position on the document-placing plate means, and holds the document for the document-placing plate means for a predetermined period of time.

摘要： An overlapped-transfer preventing paper supply device in an image-forming apparatus includes an overlapped-transfer preventing member and a rotary paper supply member in an overlapped-transfer preventing portion. A sheet-returning member returns a sheet located in the vicinity of the overlapped-transfer preventing portion to a sheet source or supply and moves from a downstream side to an upstream side of the overlapped-transfer preventing portion. A drive operates in response to a sheet-returning signal to move the sheet-returning member in a sheet-returning direction. A sheet located in the vicinity of the overlapped-transfer preventing portion can be prevented from being damaged, and jamming due to such sheet can be prevented.
