Liquid application device, image forming apparatus, and image forming system

A liquid application device for applying liquid to a plurality of media to be crimped by a crimping device, the liquid application device comprising:

• a liquid applier to apply liquid to the plurality of media;
• and
• a liquid-applier moving mechanism to move the liquid applier to a first position at which the liquid applier applies liquid to a medium on a conveyance path in the liquid application device and a second position at which the liquid applier applies liquid to the plurality of media inserted through a liquid application slit of the liquid application device,
• wherein the liquid applier includes a contact member to contact the plurality of media with liquid contained in the contact member,
• wherein the contact member includes an elastic member, and
• wherein the contact member has a first face to contact the medium on the conveyance path;
• and a second face intersecting the first face to contact the plurality of media inserted through the liquid application slit.

An image forming apparatus comprising:

• a housing;
• an image former housed in the housing to form an image on a medium;
• and
• a liquid application device for applying liquid to a plurality of media,
• wherein the liquid application device includes
• a liquid applier to apply liquid to the plurality of media;
• and
• a liquid-applier moving mechanism to move the liquid applier to a first position at which the liquid applier applies liquid to a medium on a conveyance path in the liquid application device and a second position at which the liquid applier applies liquid to the plurality of media inserted through a liquid application slit of the liquid application device, and
• wherein the liquid application device is detachably supported by the housing to apply liquid to the medium on which the image is formed by the image former.
