接触状態となっている。<First Embodiment> In FIG. 1, l is a fixing roller formed as a heating roller with a heating source inside, and has a wall thickness of, for example, 2.5 mm.
The roller has a diameter of approximately 32 mm and is made of a hollow cylindrical aluminum alloy surface layer coated with a layer of PTFE (polytetral ethylene), which is a fluororesin. The fixing roller l has either a pressure roller 2 or a fixing roller l.
The fixing roller is pressed and rotated by the fixing roller so as to form a nip portion between the fixing roller and the fixing roller. The pressure roller 2 is
For example, a 5.0 gm thick silicone rubber layer 6, which is an elastic material, is formed as an intermediate layer on the core metal, and a 50 gm thick tube-shaped fluororesin layer 7 is formed on the outer layer, with an outer diameter of 30 gm. ■
It becomes. Reference numeral 3 denotes an oil application roller for applying a release agent to the fixing roller l, which is coated on a stainless steel core with a silicone rubber layer 81 having a thickness of approximately 41 layers, and a heat-resistant felt layer 9 on the surface layer, respectively. The outer diameter is approximately 21mm. When the oil application roller 3 comes into contact with the fixing roller 1, it comes into contact with the fixing roller 1 due to its own weight and is driven to rotate. Note that the heat-resistant felt layer 9 contains l0000 as a mold release agent.
Approximately 14 g of cS silicone oil is uniformly impregnated in the longitudinal direction. This oil application roller 3 is rotatably held by a holding member 14. As shown in FIG. 3, the oil application roller 3 and the holding member 14 are integrally removable from the main body of the electrophotographic apparatus. In FIG. 2, 17 is a guide member for attaching the holding member 14, and the guide member 17 includes:
A plate spring 20 is attached, by means of which the retaining member 14 is held against movement within the guide. Further, the guide member 17 is configured to be rotatable around the bin 17A. The guide member 17 is normally biased clockwise with respect to the bin 17A since it is under a downward force by the tension spring 19. Further, in this state, the solenoid 11 having the lever 18 for pressing the guide member 17 downward is in a non-pressing state, and the oil application roller 3 is in a non-contact state with the fixing roller L. .

が転写される。From this state, the photosensitive drum (not shown) and the fixing roller rotate at the same time as the user turns on the copy signal. After the pre-rotation is completed, an optical system (not shown) begins scanning the original and exposes an image onto the photoreceptor drum. Thereafter, it is developed, and the developed image is transferred to a transfer material, which is a recording material, conveyed from a cassette or the like.

The lever 18 rotates due to the suction and pushes the end of the guide 17.

7 rotates counterclockwise around the bottle 17A, and comes into contact with the felt layer 9 of the oil application roller 3 or the fixing roller l. At this time, the groove-shaped bearings 14A at both ends of the holder 14 are provided as guides for the oil application roller shaft in substantially the same direction as the line connecting the center of the fixing roller and the center of the oil application roller. moves within the holder I4 along the bearing portion 14A, and its relative position with the halter changes. As a result, the oil application roller 3 comes into contact with the fixing roller 1 due to its own weight. In this state, the oil application roller 3 rotates following the fixing roller 1 and applies oil to the fixing roller.

When the kite 17 rotates around the bottle 17A, the holding member 14 compresses and deforms the leaf spring 20 while changing the relative position of the kite 17. In other words, the holding member 14 is subjected to a force A'1 through the leaf spring 20 attached to the kite j'7. Mouth: It becomes a heavy contact force against the sea urchin.

The rotation speed becomes 1'1f in 80" increments. Figure 5 (A)
The state shown by the solid line "C" represents the standby state when the amount of oil applied is large, and the state shown by the solid line "C" shows the standby state when the amount of oil applied is large. At the same time as the copy signal is turned on, a predetermined copying block U1 process is started, a signal from the DC controller is issued by the above-mentioned timer, the solenoid 1-U' is de-energized, and the guide 17 begins to rotate. (The oil application a-ra comes into contact with the fixing port a. After that, the guide 17
The lever part of the kite 17 comes in contact with the kite 15 and controls its rotation. At this time, the guide 17 and Holter
The relative position of 14 changes greatly, and the amount of change causes the leaf spring 20 to deform. The pressure corresponding to this deformed part?
The contact operation is completed and the oil application operation is performed through 14. Then, when the fixing temperature control temperature is switched to a lower temperature, λ is applied to the oil application roller. Then, the half-rotation taratch rotates without turning, and the eccentric cam 15 that is linked to it rotates 180 degrees as shown in Figure 5 (B).
Rotate. Then, part of the lever of the guide 17 and the eccentric cam 1
5, the contact position changes, and the amount of rotation of the guide 17 is controlled to be smaller. Then, when the contact movement is completed, the plate springs 2
The amount of deformation of 0 is controlled accordingly, and the force applied to the coating roller is controlled to be low.

Compared to the case shown in Figure CA), the amount of oil discharged decreases. However, according to this embodiment, when the temperature control temperature is high, a stronger pressure is applied, and when it is low, the pressure is lowered.
(Instead of the eccentric cam linked to the half-rotation crank described in 71-1), a stopper for controlling the rotation of the guide 17 is used.
It is also possible to use C1 shape memory alloys or bimetals.
