PROBLEM TO BE SOLVED: To provide a sheet feeding device capable of saving an installation space, and an image forming device including the sheet feeding device.SOLUTION: A sheet feeding device has an intermittent transmitting portion for intermittently transmitting rotary motion of feeding means on a feeding rotary shaft. The intermittent transmitting portion is composed of a main transmitting portion which can be moved by a moving member on the feeding rotary shaft, and integrally rotated with the feeding means; and a following transmitting portion which can rotate on the feeding rotary shaft, and is at a fixed position to the feeding rotary shaft. Motion transmission is carried out by engaging an engaging portion of the main transmitting portion with an engaged portion of the following transmitting portion. Motion transmission interception is carried out by contacting a stopper portion with a downstream position of the following transmitting portion to prevent motion action, and releasing the engagement between the engaged portion of the following transmitting portion and the engaging portion of the main transmitting portion.SELECTED DRAWING: Figure 41 【課題】設置スペースを削減可能なシート給送装置及びこれを備えた画像形成装置を提供する。【解決手段】給送手段の回転運動を給送回転軸上で間欠伝達するための間欠伝達部を有し、該間欠伝達部は、前記給送回転軸上で移動部材により移動可能で、かつ、前記給送手段と一体的に回転する主伝達部と、前記給送回転軸上で回転可能で、かつ、前記給送回転軸に対して一定位置にある従伝達部とからなり、運動伝達は、前記主伝達部の係合部を前記従伝達部の被係合部に係合させることで行い、運動伝達遮断は、前記従伝達部の下流位置にストッパ部を接触させ運動動作を妨げ、前記従伝達部の被係合部を前記主伝達部の係合部と係合解除する。【選択図】図４１
