摘要： PROBLEM TO BE SOLVED: To provide a sheet conveying device and an image forming device realizing a high productivity and capable of conveying a sheet group without changing a conveying timing of the sheet. SOLUTION: A sheet 1P of sheets superposed and continuously conveyed is branched by a flapper 210 and is introduced to a sheet conveying passage. A buffer roller 202 is accelerated and conveyed at a high speed and after the sheet 1P is left from a sheet 2P and is conveyed, it is merged with the sheet 2P at a first sheet conveying passage. At the time of merging, a superposing state of the sheet 1P and the sheet 2P is made the same as before branched.
