Abstract

An adhering ink absorption mechanism for a wiper cleaner that facilitates mounting of an ink absorber and replacement of the ink absorber, includes an ink absorber to absorb ink adhering to a wiper by being brought into contact with the wiper, and an ink absorber supporting portion to support the ink absorber at an upper position of the wiper in a state where a contact region with the wiper is released to enable the wiper to be brought into contact with the ink absorber from below by a lifting operation. The ink absorber has a flat plate shape, and includes a placed portion placed on and supported by the ink absorber supporting portion, and an extension region portion bent at an edge of the placed portion and extending downward.
