Abstract
A fixing apparatus includes a roller for fixing a toner image formed on a supporting element, a container for receiving an offset preventing liquid and an element for applying the offset preventing liquid on the surface of the roller. The liquid applying element is partially immersed in the offset preventing liquid and it includes a liquid applying member for applying the liquid from the end surface of the member by capillary action, and a member adjacent the end surface to affect the capillary action by squeezing the liquid applying member to control the amount of the liquid applied . Felt is preferably used for the liquid applying member.
Claims5
A fixing apparatus comprising roller means for fixing a toner image formed on a supporting element, a vessel containing an offset preventing liquid, a member, having an end surface contactable with said roller means, for applying, by capillary action, the offset preventing liquid on the surface portion of said roller means which is utilized for the fixing action, means provided adjacent to said end surface of said liquid applying member for controlling the capillary action to thereby control the amount of liquid applied to said roller means by said liquid applying member, means for supporting said liquid applying member, and means for moving said support means toward and away from said roller means such that said end surface of said liquid applying member is movable into and out of contact with said roller means.
