Abstract:
A fixing apparatus comprising:a heating mechanism including: a heating object which is either a hollow cylinder or an endless belt, and in which a predetermined heat is supplied to a thermally fusible material and a base material holding said thermally fusible material, and either a peripheral surface of said cylinder or a belt surface of said belt, constituting said heating object, is moved at a predetermined speed; a pressure supply mechanism which supplies a predetermined pressure to said heating object with said thermally fusible material and base material disposed between the pressure supply mechanism and said heating object, and whose peripheral surface is followed and moved by moving either the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object, at the predetermined speed; a heating object heating mechanism which is set in said heating object, and allows said heating object to generate heat; a thermally fusible material recovering member which is brought in contact with the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object, at the predetermined pressure, and which can recover said thermally fusible material adhering to the peripheral surface of said cylinder or the belt surface of said belt; a thermally fusible material recovering member renewing mechanism to move a region of said thermally fusible material recovering member brought in contact with the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object, at the predetermined pressure by a predetermined amount, when a predetermined amount of said thermally fusible material is absorbed by said thermally fusible material recovering member; and a heating object temperature detecting mechanism which detects a temperature of the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object; a thermally fusible material recovering member renewing mechanism control apparatus which moves the region of said thermally fusible material recovering member brought into contact with the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object, at a predetermined timing; and a temperature rise time count mechanism to measure a time necessary for said heating object temperature detecting mechanism to detect that the temperature of the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object, has reached a predetermined temperature, wherein said thermally fusible material recovering member renewing mechanism control apparatus changes an amount of movement of said thermally fusible material recovering member based on the time counted by said temperature rise time count mechanism, when a region of said thermally fusible material recovering member brought in contact with the peripheral surface of said cylinder or the belt surface of said belt, constituting said heating object, is moved at a predetermined timing.
