| 主权项 | 1. A sheet conveying device that passes a sheet to a nip portion formed between first and second rotating bodies and conveys the sheet, the sheet conveying device comprising: a separation state determining unit configured to determine a separation state between the sheet having passed the nip portion and a surface of the first rotating body; a sheet separating unit configured to allow force to act on the sheet, the force being in a direction of being separated from the surface of the first rotating body; and a control unit configured to control the force acting on the sheet by the sheet separating unit according to a result of the separation state determining unit, wherein the separation state determining unit includes an illumination unit configured to illuminate an outlet side of the nip portion in a sheet passing direction, an imaging unit configured to image a tip portion of the sheet having passed the nip portion, and an acquisition unit configured to acquire positional information of a tip of the sheet based on image data obtained by the imaging unit, and the separation state between the sheet and the first rotating body is determined based on the acquired positional information of a tip of the sheet. | ||
