Abstract:
1. A fixing device comprising: means for heating, the heating means is formed into a hollow cylinder or an endless belt, has a outer surface of the cylinder or a belt surface of the belt movable at a predetermined speed, and the heating means can supply predetermined heat to a hot-melt substance and a medium holding the hot-melt substance; means for applying pressure, the pressure applying means has a outer surface that can move following the outer surface of the cylinder or the belt surface of the belt when the outer surface of the cylinder or the belt surface of the belt of the heating means is moved at the predetermined speed, and the pressure applying means applies a predetermined pressure to the heating means while interposing the hot-melt substance and the medium between the heating means and the pressure application mechanism; means for exciting the heating means, the exciting means is set to increase a temperature of the heating means, and allows the object to generate heat; means for taking a hot-melt, the taking means is brought into contact with the outer surface of the cylinder or the belt surface of the belt of the heating means at a predetermined pressure, and the taking means can take the hot-melt substance attached to the outer surface of the cylinder or the belt surface of the belt; means for changing the taking means, the changing means can move the taking means by a predetermined amount in a region where the taking means is brought into contact with the outer surface of the cylinder or the belt surface of the belt of the heating means at the predetermined pressure when a predetermined amount of the hot-melt substance is absorbed in the taking means; means for controlling the changing means, the controlling means moves the taking means at a predetermined timing in the region where the taking means is brought into contact with the outer surface of the cylinder or the belt surface of the belt of the heating means; and means for checking an end portion of the taking means, wherein, when the checking means checks that a remaining portion of the taking means reaches a predetermined amount up to the end portion of the taking means, an operation timing of the changing means by the controlling means is delayed at a predetermined ratio.
