Embodiment Construction

[0022] Embodiments of the present invention will be described below with reference to the drawings. First, a schematic configuration of a color printer as an image forming apparatus will be described, and then a fixing unit and its cleaning mode will be described.

[0023] (Schematic configuration of a color printer as an image forming apparatus)

[0024] Such as figure 1 As shown, the image forming apparatus 1 of this embodiment is a tandem color printer. Four toner tanks 102Y, 102M, 102C, and 102K corresponding to each color (yellow, magenta, cyan, and black) are provided in the tank housing portion 101 located above the main body of the image forming apparatus in a detachable (freely replaceable) manner. .

[0025] The intermediate transfer unit 85 is disposed below the tank housing portion 101 (referred to as setting after arrangement, or setting after positioning). Imaging portions 4Y, 4M, 4C, and 4K corresponding to the respective colors (yellow, magenta, cyan, and b...

Abstract

In the image forming apparatus of the present invention, the user can easily confirm whether the removal of the toner contamination is completed while removing the toner contamination adhering to the rotor of the fixing unit through a normal printing operation. By setting the image forming apparatus to the cleaning mode, a cleaning area is formed on the front end side in the conveyance direction of the sheet member P, and a cleaning confirmation area is formed on the rear end side in the conveyance direction. The two regions are formed in the conveyance direction of the sheet member P with a length equal to or greater than the circumference of the rotor of the fixing unit. When the unfixed toner image formed in the cleaning area passes through the nip between the two rotators of the fixing section, it exhibits cohesiveness by controlling the heat lower than that of the usual nip, and Contamination on the surface of the rotor is absorbed without deflection in the rotor. Whether the contamination on the surface of the rotor is completely absorbed in the cleaning area is confirmed by checking whether the contamination of the rotor in the cleaning confirmation area is transferred and adhered.

Description

technical field [0001] The present invention relates to an image forming apparatus, especially an image forming apparatus of a copier, a printer, a plotter, a facsimile machine, or their multifunctional peripherals. Background technique [0002] Conventionally, as a fixing unit used in an image forming apparatus such as a printer or a copier, a heat roller type fixing unit is known. This heat roller type fixing unit includes a rotating fixing roller provided with a heat source such as a halogen heating tube inside, and a pressure roller rotating while being pressed against the fixing roller. Then, the recording medium on which the unfixed toner image is placed passes through a fixing nip formed between the two rollers, and the unfixed toner image is melted at the fixing nip and fixed to the recording medium. [0003] On the other hand, due to the increasing demand for energy saving and shortened standby time of the fixing unit in recent years, a fixing rotor or a pressurizi...
