A bookbinding apparatus for trimming and cutting a bunch of sheets subjected to bookbinding using an adhesive, comprising: adhesive applying means for applying the adhesive to a back portion of the bunch of sheets; a transport path for feeding the bunch of sheets with the adhesive applied thereto to a predetermined trimming position; a trimming blade disposed in the trimming position; bunch position changing means disposed in the transport path to change a position of the bunch of sheets in the trimming position; a blade receiving member disposed opposite to the trimming blade with the bunch of sheets in the transport path therebetween, and having at least first and second blade receiving areas with different blade receiving surfaces contacting with the trimming blade; and driving means positioning the trimming blade between a cut position for bringing the trimming blade into contact with the blade receiving member and a spaced waiting position, shift means selectively shifting one of the first and second blade receiving areas to a predetermined trimming position, and control means for controlling the shift means and the driving means, said control means being configured such that when an upper-edge portion and a lower-edge portion of the bunch of sheets, which have the adhesive, are trimmed by the trimming blade, the blade receiving member is shifted to the first blade receiving area, and when a fore-edge portion without the adhesive is trimmed by the trimming blade, the blade receiving member is shifted to the second blade receiving area.
