14. A medium processing apparatus, comprising:
a conveyor configured to convey a medium;
a liquid applier configured to apply liquid to the medium conveyed by the conveyor; and
a crimper configured to press and deform a medium bundle including at least one medium to which the liquid is applied by the liquid applier, to bind the medium bundle,
wherein the liquid applier is configured to perform application of the liquid to only some media constituting the medium bundle, so that not all of the media constituting the medium bundle have liquid applied thereto,
wherein the conveyor includes a conveyance passage to convey the medium to a tray on which the media are to be placed, and a retreat conveyance passage that is disposed upstream from the tray in a conveyance direction of the medium and is different from the conveyance passage, and
wherein the conveyor temporarily conveys a medium to which the liquid is not applied by the liquid applier to the retreat conveyance passage, and then overlays a subsequent medium, which is conveyed after the medium to which the liquid is not applied, with the medium to which the liquid is not applied, and conveys the subsequent medium overlaid with the medium to the tray, and the liquid applier applies the liquid to the subsequent medium overlaid on the medium.
