Abstract
The present invention provides a liquid application device and an ink jet recording apparatus each capable of reducing deterioration in application quality due to an increase in the number of times of use of a roller, thereby improving durability. The present invention includes an application roller which applies liquid to an application medium, and a liquid retention member which retains the liquid in a liquid retention space formed by making the application roller be in contact with the retention member. With this structure, a pool of the liquid is formed, with rotation of the application roller, in an area upstream of a contact area, in a rotational direction, between the application member and the retention member at a side where a surface of the application member enters the contact area therebetween.
