1. A medium processing apparatus comprising:
a conveyor configured to convey a medium;
a liquid applier configured to apply liquid to a part of the medium conveyed by the conveyor, the medium being at least one medium;
a crimper configured to press and deform a bundle of media including the medium to which the liquid is applied by the liquid applier, to bind the bundle of media,
the liquid applier including:
a liquid application member configured to apply the liquid to a position to be bound by the crimper on the medium;
a retained liquid amount detector configured to detect an amount of the liquid retained by the liquid application member,
wherein the liquid applier includes a pair of counter electrodes on the liquid application member, and
wherein the retained liquid amount detector is configured to detect the amount of the liquid retained, based on an electric signal acquired by conduction of the pair of counter electrodes.
