Zusammenfassung:	To provide a sheet carrier device and image formation device, preventing generation of a control delay when controlling the carrying speed of a sheet.SOLUTION: A sheet carrier device includes: a speed detection roller for detecting the carrying speed of a sheet by being driven to rotate in contact with the carried sheet, and a temperature control section executing temperature control so that an ambient temperature of the speed detection roller becomes a prescribed temperature. The sheet carrier device includes a roller heating section for heating the speed detection roller, and the temperature control section controls the roller heating section so that the temperature of the speed detection roller becomes a prescribed temperature.SELECTED DRAWING: Figure 1 【課題】用紙の搬送速度を制御する際に制御遅延の発生を防止することが可能な用紙搬送装置および画像形成装置を提供する。【解決手段】用紙搬送装置は、搬送される用紙に接触して従動回転することによって用紙の搬送速度を検知する速度検知ローラーと、速度検知ローラーの周囲温度が所定温度となるように温度制御を行う温度制御部と、を備える。用紙搬送装置は、速度検知ローラーを加熱するローラー加熱部を備え、温度制御部は、速度検知ローラーの温度が所定温度となるようにローラー加熱部を制御する。【選択図】図１
