Medium processing apparatus and image forming system incorporating same

A medium processing apparatus comprising:

• a liquid applier configured to apply liquid on at least one medium;
• a post-processing device configured to perform a combination of:
• various types of post-processes including:
• a liquid application crimp binding;
• and
• a crimp binding;
• and
• various types of bindings including:
• a dual binding;
• a parallel binding;
• and
• an oblique binding,
• on a bundle of media including the at least one medium for a number of times;
• and
• circuitry configured to change the number of times of the post-process according to the combination of:
• the various types of the post-processes;
• and
• the various types of the bindings,
• to be performed,
• wherein the post-processing device includes a crimper to perform the crimp binding, that presses and deforms the bundle of media in a thickness direction of the bundle of media to bind the bundle of media, for a number of times, as the post-processes, and
• the post-processing device includes a stapler to perform a staple binding on the bundle of media,
• the circuitry is further configured to:
• determine whether the crimper performs the crimp binding based on a remaining amount of the liquid held by the liquid applier;
• and
• control the stapler to perform the staple binding based on a determination that the crimper does not perform the crimp binding.
