An image forming apparatus recognizes a requesting user who has requested execution of a printing job stored in a memory portion, and in a case where a distance between a mobile terminal owned by the requesting user and the image forming apparatus has become not more than a first threshold value, the image forming apparatus performs control so that interrupt printing is performed in which the printing job of the requesting user is started, and so that another printing job is not resumed until a prescribed time length has elapsed after completion of the printing job of the requesting user.
