Medium processing device, storage medium, and image forming system

A medium processing apparatus, comprising:

• a liquid applier configured to apply liquid to a liquid application position of a medium;
• a crimper configured to press and deform at least a part to which the liquid is applied by the liquid applier, to bind a plurality of media including the medium to which the liquid is applied;
• a stapler configured to perform stapling with a staple on a medium bundle including the plurality of media;
• circuitry configured to:
• control operations of the crimper, the liquid applier, and the stapler;
• selectively switch between first binding performed by the liquid applier and the crimper and second binding performed by only the stapler, in accordance with information on the medium or a binding position at which the medium bundle is bound by the crimper;
• execute the first binding with the liquid applier and the crimper when the information on the medium is less than a first threshold number of media;
• and
• execute the second binding with only the stapler when the information on the medium is equal to or greater than the first threshold number of media;
• and
• an operation device configured to set the first threshold number of media and a second threshold number of media that is less than the first threshold number of media.
