Application apparatus and image forming apparatus
Abstract:
An application apparatus includes: a medium conveying device which holds and conveys a medium in a predetermined conveyance direction; an application roller which applies a liquid to the medium held by the medium conveying device; an application roller rotating device which rotates the application roller at a predetermined rotational speed; a measuring roller which feeds a predetermined measured amount of the liquid to the application roller; a measuring roller rotating device which rotates the measuring roller at a predetermined rotational speed; a first moving device which causes relative movement between the application roller and the medium conveying device to change a distance between the application roller and the medium conveying device; a second moving device which causes relative movement between the application roller and the measuring roller to change a distance between the application roller and the measuring roller; and a movement controlling device which controls the second moving device in such a manner that, when the application roller and the medium are brought into abutment with each other from a state in which the application roller and the medium are separated from each other, a front end part of the medium in terms of the conveyance direction abuts with an abutment position on a circumferential surface of the application roller when the application roller and the measuring roller are brought into abutment with each other from a state in which the application roller and the measuring roller are separated from each other.
