Filed: 2007-07-30
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the adverse effect of a foamy fixing liquid remaining on an application roller in a fixing device in which the foamy fixing liquid is applied to toner or the like.  <P>SOLUTION: A film of foamy fixing liquid, the thickness of which is controlled by a film thickness control blade 22, is formed on the application roller 22. The film of foamy fixing liquid is pressed against an unfixed toner layer on a paper sheet 25, thereby causing the foamy fixing liquid to permeate through the toner layer. The foam of fixing liquid remaining on the application roller 20 without being attached to the toner layer is sandwiched and defoamed between a defoaming roller 23 and the application roller 20 and consequently re-liquefied. Since the bulk density of the foamy fixing liquid is low, the volume of the foamy fixing liquid decreases from one several tenth to one several hundredth as a result of re-liquefying it. The re-liquefied fixing liquid is absorbed by a liquid absorbing sponge (not shown) disposed at an end of the application roller 20.  <P>COPYRIGHT: (C)2009,JPO&INPIT
