An image forming system includes: a transporter that transports an object; a transfer unit that transfers an image onto the object transported by the transporter; a fixing unit that fixes, onto the object, the image transferred by the transfer unit; and a processor configured to: in a first mode, exert control to obtain the state in which the fixing unit enables an image to be fixed; and, in a second mode, exert control to obtain the state in which the fixing unit does not fix an image.
