    摘要： To provide an image forming apparatus that can highly accurately position and convey, even if an inter-sheet distance of sheets to be conveyed is reduced, the sheets from registration rollers to a transfer position when a toner image on an image bearing member moving at process speed is transferred onto the sheet in the transfer position. A sheet fed from a paper feeding cassette by a pulse-motor driven paper feeding roller is conveyed to pulse-motor driven registration rollers by pulse-motor driven conveying rollers. When the sheet is conveyed to the transfer position according to restart of the registration rollers, the sheet is conveyed by the registration rollers at sheet conveying speed different from the process speed before the leading end of the sheet reaches the transfer position and is conveyed at the process speed after that.

    摘要： A paper feeding cassette includes: a cassette case configured to store sheets; a sheet tray on which the sheets are stacked, the sheet tray being rotatably attached to the cassette case; a push-up member configured to push up the sheet tray and rotate the sheet tray in one direction when driving force is input and release the push-up of the sheet tray to allow rotation of the sheet tray in the other direction when the input of the driving force is interrupted; and a buffer member configured to be nipped by the cassette case and the sheet tray and elastically deformed when the sheet tray rotates in the other direction. The buffer member is located, when viewed from a stacking direction of the sheets, in an area closer to a rotation axis of the sheet tray than a distal end of the sheet tray that is most distant from the rotation axis in the sheet tray.

    摘要： In an image transferring apparatus of the invention, a relay unit, which is provided in a main body frame and includes a conveyance switching mechanism to eject a sheet on which an image is fixed by a fixing section to a sheet ejection section or to switch back the sheet in the middle of ejection, can be pulled out, and a automatic duplex unit to guide the switched back sheet to an image forming section is mounted to the main body frame to be capable of being detached. An intermediate unit to guide the sheet switched back by the relay unit, together with the fixing section, is fixed and placed in the main body frame. The intermediate unit is provided with a guide member to be capable of being opened and closed between a guide position for the switched back sheet and an open position opposite to the guide position. The guide member always receives a spring force toward the open position, and when the automatic duplex unit is mounted to the main body frame, the guide member is moved to the guide position by contact with a pressing body of the automatic duplex unit side, and when the automatic duplex unit is detached from the main body frame, the guide member is opened to the open position by the spring force.
