PROBLEM TO BE SOLVED: To provide an image forming device capable of more surely realizing accurate alignment and color matching in constitution where a light reflection member backing up the rear surface of an endless belt is provided to detect a reference toner image. SOLUTION: A roller 200 is rotatably provided as a pressing member for pressing a transfer carrying belt 60 against a reflection member 70 side. The roller is made to abut on the transfer carrying belt on a more upstream side in a transfer carrying belt moving direction than a light reflecting position. The roller presses the transfer carrying belt against the reflection member side while rotating with the transfer carrying belt with the carrying of the transfer carrying belt, so that the floating of the transfer carrying belt from the light reflection member or the waviness thereof is prevented. |
