A finishing device with an output unit that outputs a recorded sheet on which an image is recorded, a sheet stacker that receives the recorded sheet from the output unit and on which the recorded sheet is stacked, and a reference surface against which the recorded sheet on the sheet stacker is aligned. A binding unit binds a bundle of the recorded sheets aligned against the reference surface and a sheet pressing member presses an end portion of the recorded sheet toward the sheet stacker. The end portion is closer to the reference surface, and a first moving and pressing unit moves the recorded sheet toward the reference surface while the sheet pressing member presses the end portion of the recorded sheet.
