た高電位コントラストの静電潜像が順次に形成される。Reference numeral 16 denotes a drum-shaped electrophotographic photosensitive drum that is rotated at a predetermined circumferential speed in the direction of the arrow. The drum 16 is subjected to prior history removal in a pre-exposure charge remover 45, uniformly charged with positive or negative charges in a primary discharger 41, and charged with a DC corona of opposite polarity to the primary discharger 41 in a secondary discharger 42. The entire surface is exposed to electric discharge or AC corona discharge and light image exposure (slit exposure) from the optical systems 34 to 39, and then the entire surface is exposed by the entire surface exposure device 43, so that a high potential corresponding to the exposed light image pattern is formed on the peripheral surface. Contrasting electrostatic latent images are sequentially formed.

The transfer material continues to be wound around the transfer drum 45 and held there. The photosensitive drum 16 continues to be driven to rotate, and a cleaner 47 removes the residual toner image after transfer.

is a fixing roller, for example, HTV is applied to the surface of the metal pipe 1a.
It has a structure covered with a silicone rubber layer 1b. Reference numeral 2 denotes a pressure roller, which is constructed by, for example, a metal pipe 2a whose surface is coated with an HTV silicone rubber layer 2b. 3 is a heater built into the fixing roller 1, and 4 is a temperature detection member such as a thermistor for detecting the surface temperature of the fixing roller l.

っている。Now, when the recording material 6 carrying the unfixed toner image 5 passes between the fixing roller l and the pressure roller 2, the toner image 5 is heated and fixed on the recording material 6 by the heat supplied by the heater 3. The temperature of each roller 1, 2 is set to a temperature that can be heated and melted according to the characteristics of each toner, for example, the temperature of the fixing roller 1 is set to 180°C, and the temperature of the pressure roller 2 is set to 180°C.
The heater 3 is turned on by the detection signal of the thermistor 4,
The temperature is controlled so that the temperature is maintained at the set temperature by turning it off.

てしまう欠点がある。In this way, in the conventional heat fixing device, the fixing roller l
The temperature of the pressure roller 2 is set higher than that of the pressure roller 2. Furthermore, in this case, when the fixing operation is performed continuously, the heat of the fixing roller 1 is absorbed by the edge recording material 6 and is not transmitted to the pressure roller 2, so the temperature of the pressure roller 2 is low. There is.

触するＩ−側のイエローのトナーは溶けやすいが、ド側
すなわち記録材表面近傍のシアントナーは溶けにくい。Particularly in electrophotographic color duplex machines like the example shown in Figure 1, three or four colors of toner are used for full-color copying, so the amount of toner needed for monochrome copying and for the recording material is large. It's going to be different. In particular, if the unfixed toner image at the time of full-color copying has a three-layer structure of yellow toner, magenta toner, and cyan toner in order from L, there is a large amount of toner, so that Yellow toner dissolves easily, but cyan toner on the do side, that is, near the surface of the recording material, is difficult to dissolve.
そこで、トナー全体をよく溶融させるために定着ローラ
ｌを高い温度に設定すると、トナー表面がｉ“着ローラ
ｌにオフセットする現象が生ずる。Therefore, if the fixing roller l is set at a high temperature in order to melt the entire toner well, a phenomenon occurs in which the surface of the toner is offset to the fixing roller l.
このためフルカラーコピ一時は記録材裏面より加ｊ 熱
を行う高い温度の背面加熱ヒータが必要となる。For this reason, full-color copying requires a high-temperature backside heater that heats the recording material from the backside.
一方、モノカラーコピ一時はｌ−記のような定着の条件

Depending on the state of the toner, that is, the temperature of the fixing roller is set higher than the temperature of the pressure roller for single-color copying, and the temperature of the pressure roller is set higher than the temperature of the fixing roller for multi-color copying, such as full-color copying. By doing so, it is possible to improve the color mixing property of the toner during full color printing, improve image quality and fixing performance, and prevent offset 1F, while saving power consumption during monochrome printing. To give an example, the power consumption is 5 when fixing 1000 sheets of A4 recording material at once in full color.
In contrast to the KW required, we were able to reduce the power consumption to 3KW for the monochrome system.
