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.
