Side causes with paper P separating plates 60 separated from fixing band 21 etc..
Also it is possible to outside the heating tube 25 of the side of fixing band 21 or instead added as thermal source being arranged on
Heat pipe is arranged on the side of backer roll 31 as pressurization rotor.Alternatively, it is also possible to be arranged on point of the side of fixing band 21
From outside plate 60 or instead be to be arranged on the side of backer roll 31 with paper P separating plate as separation.Separating plate 60 is located at
The downstream of paper conveyance direction is more used than the fixing nip portion N that fixing band 21 and backer roll 31 are formed, and is arranged to determining
Shadow bands 21 and backer roll 31 it is at least one opposite and right, be so that by the recording materials in fixing nip portion from fixing band or add
The flat part of pressure roller separation.
Here, fixing band 21 is the thin endless belt with pliability, arrow A directions (counter-clockwise direction) in fig. 2
Upper rotation.In addition, fixing band 21 stacks gradually since as the inner peripheral surface side with clamping the face for forming the sliding contact of component 26
There are substrate layer, elastic layer and release layer, its all thickness is set at below 1mm.
The thickness of the substrate layer of fixing band 21 is 30 μm~100 μm, by the metal material or polyimides of nickel, stainless steel etc.
Deng resin material formed.
The thickness of the elastic layer of fixing band 21 is 100 μm~300 μm, by silicon rubber, foaminess silicon rubber and fluorine element rubber
The elastomeric material of glue etc. is formed.By setting elastic layer, the small of the surface of fixing band 21 would not be formed in fixing nip portion N
Bumps, heat will be evenly transferred to use in the toner image T on paper P, thus may refrain from the generation of orange peel image.
The thickness of the release layer of fixing band 21 is 10 μm~50 μm.In addition, the release layer be by PFA (tetrafluoroethene with
The sour copolymer of perfluorinated alkoxy vinyl, PTFE (polytetrafluoroethylene (PTFE)), polyimides, PEI, PES (polyether sulfone) etc.

In addition, the diameter of fixing band 21 is set to 15mm~120mm.Further, in the present embodiment, fixing band 21
Diameter is set to 30mm or so.
Heat transfer member 22, enhancing component 23, heating tube 25 and clamping shape are fixedly installed in the inner peripheral surface of fixing band 21
Into component 26 etc..
Clamping is formed in component 26 is formed the concavity of the curvature along backer roll 31 towards the face of the side of backer roll 31.
Thus, due to being to be sent out according to the curvature of backer roll 31 from fixing nip portion N with paper P, it becomes possible to after suppressing fixing process
The problem of absorption with paper P with fixing band 21 without separating.
Further, in the present embodiment, although the shape that the clamping for forming fixing nip portion N is formed to component 26 is formed
For along the concavity of the curvature of backer roll 31, but the clamping that form fixing nip portion N can also be formed to the shape shape of component 26
As plane.
That is, can by clamp be formed component 26 and backer roll 31 it is opposite and to face be formed as flat shape.By
This, fixing nip portion N shape is almost parallel relative to the image surface with paper P, because of fixing band 21 and with paper P adhesion
Improve and fixation performance is improved.Further, because the curvature of the fixing band 21 of fixing nip portion N outlets side increases,
So allow for easily being separated from fixing band 21 with paper P by what fixing nip portion N was sent out.
Heat transfer member 22 be by the metal sheet that thickness is 0.1mm bend to one end and the other end be it is opposite and to
The tubular part of approximately C-shaped shape.Heat transfer member 22 be formed in addition to fixing nip portion N position directly with fixing band 21
Inner peripheral surface is opposite and right, be formed towards in fixing nip portion N position inner side concavity while, be configured to formed with
The recess that clamping forms the opening of component 26 is arranged.
Support is fixed on the side plate of fixing device 20 in the width both ends of heat transfer member 22.In addition, heat transfer structure
Part 22 heats after being heated by the radiant heat (radiant light) of heating tube 25 to fixing band 21.That is, heat transfer member
22 are themselves directly heated by heating tube 25, and make it that fixing band 21 is indirect by heating tube 25 by means of heat transfer member 22
Heat on ground.
Material as heat transfer member 22 can use the metal heat transfer body of aluminium, iron, stainless steel etc. (to have the gold of thermal conductivity
Category).In addition, by the way that the thickness of heat transfer member 22 is set in into below 0.2mm, it becomes possible to improve heat transfer member 22 or fixing band 21
The efficiency of heating surface.Further, in the present embodiment, heat transfer member 22 is formed by the stainless steel plate that thickness is 0.1mm.
Heating tube 25 is halide electrothermal pipe or carbon heat-generating pipe, and its both ends is fixed on the side plate of fixing device 20.So
Afterwards, the radiant heat of the heating tube 25 of output control, heat transfer member 22 are carried out by the power supply unit by image forming device body
Heated.Further, by heat transfer member 22, fixing band 21 is in the position beyond fixing nip portion N by universally
After heating, heat can be applied to from the surface of heated fixing band 21 with the toner image T on paper P.
Further, the output control of heating tube 25 be according to opposite with the surface of fixing band 21 and to thermistor etc. temperature
Degree sensor 40 is carried out to the testing result of belt surface temperature.Pass through the output control of such heating tube 25, it becomes possible to
The temperature (fixing temperature) of fixing band 21 is set in desired temperature.
In this way, the part that the fixing device 20 in present embodiment is not only fixing band 21 is locally heated, but
Essentially universally it is heated on whole circumference direction come fixing band 21 by heat transfer member 22.Therefore, even if dress
When being set to high speed, fixing band 21 can also be sufficiently heated and suppress fixing bad generation.
That is, due to can efficiently heat fixing band 21 by relatively simple composition, it is pre- shortening
While hot time or first time-write interval, additionally it is possible to reach the miniaturization of device.
Here, the spacing G of the fixing band 21 under normal temperature and heat transfer member 22 is (between in the position beyond fixing nip portion N
Away from) preferably bigger than 0mm at below 1mm (0mm < G≤1mm).Thus, it becomes possible to suppressing because of heat transfer member 22 and determining
While the problem of area of the sliding contact of shadow bands 21 increases and causes the abrasion of fixing band 21 to accelerate, for heat transfer member 22
The reduction of the efficiency of heating surface of fixing band 21 is suppressed caused by being separated excessively with fixing band 21.
Further, by the way that heat transfer member 22 is set close to fixing band 21, due to the fixing band with pliability
21 circular posture obtains the maintenance of heat transfer member 22 to a certain extent, becomes to cause so can just reduce fixing band 21
Deterioration or breakage.
In addition, for the abrasion that heat transfer member 22 and fixing band 21 can also reduce even if sliding contact fixing band 21, also
The fluorenone as lubricant can be applied between fixing band 21 and heat transfer member 22.
Further, in order to reduce the slip moving resistance of heat transfer member 22 and fixing band 21, for the inner circumferential with fixing band 21
, can also be with material of the coefficient of friction less than fixing band 21 come shape for the sliding contact surface of the heat transfer member 22 of face sliding contact
Into heat transfer member 22.Alternatively, it is also possible to form the superficial layer being made up of the material comprising fluorine element in the inner peripheral surface of fixing band 21.
As support clamping formed component 26 supporting member enhancing component 23 be used for strengthen and support to be formed it is fixing
The clamping of clamping part N forms component 26, and is fixedly installed on the inner peripheral surface side of fixing band 21.
Strengthen the length of the width (long side direction) of component 23 and clamping forms width (the long side side of component 26
To) equal length, its width both ends fixed support on the side plate of fixing device 20.
Then, form component 26, fixing band 21 by strengthening component 23 by means of clamping or slide mobile sheet material 28 come with
The abutting of backer roll 31, it may refrain from the clamping in fixing nip portion N and formed component 26 because of the plus-pressure by backer roll 31
And caused larger deformation.
Further, component 23 is strengthened in order to meet above-mentioned function, with the metal material of the high mechanical strength of stainless steel or iron etc.
To be formed preferably.In addition, in strengthening component 23 and heating tube 25 it is opposite and to face part or all in, can also set
Put thermal insulation member or carry out BA processing or mirror ultrafinish processing.
Thus, because the heat (heat heated to enhancing component 23) from heating tube 25 towards enhancing component 23 be used to conduct heat
The heating of component 22, so just can further improve the efficiency of heating surface of fixing band 21 or heat transfer member 22.
In fixing nip portion, a diameter of 30mm for the backer roll 31 that N opening position abuts with the outer peripheral face of fixing band 21 is left
The right side, and elasticity layer 33 is formed on the plug 32 of hollow structure.Further, can also be set in the inside of the plug 32 of hollow structure
Put the thermal source of halide electrothermal pipe etc..
The elastic layer 33 of backer roll 31 is formed by the material of silicon rubber, foaminess silicon rubber or fluorine unpigmented rubber etc..
Further, the thin release layer being made up of PFA or PTFE etc. can be also set on the top layer of elastic layer 33.
Backer roll 31 is crimped with fixing band 21, and required fixing nip portion N is formed between the component of both sides.Backer roll
31 width both ends are supported for rotating on the side plate of fixing device 20 by means of bearing.In addition, adding
Be provided with the drive gear meshed gears with drive mechanism in pressure roller 31, backer roll 31 by drive mechanism transmission come rotation
Driving force is rotated driving on arrow B directions (clockwise direction) in fig. 2.
When the spongy material by foaminess silicon rubber etc. is to form the elastic layer 33 of backer roll 31, because can drop
The low plus-pressure acted in fixing nip portion N, so can just mitigate the bending for producing and being formed in clamping in component 26.
Further, because the thermal insulation of backer roll 31 is improved, hot not easily moveable arrive of fixing band 21 is pressurizeed
The side of roller 31, so just improving the efficiency of heating surface of fixing band 21.
In addition, in the present embodiment, although the diameter of fixing band 21 it is identical with the diameter of backer roll 31 but it is also possible to be
The diameter of fixing band 21 is less than the diameter of backer roll 31.At this moment, because the curvature of the fixing band 21 in fixing nip portion N is greater than
The curvature of backer roll 31, it is easy for separating from fixing band 21 with paper P from what fixing nip portion N was sent out.
In addition, the diameter of fixing band 21 can also be formed larger than the diameter of backer roll 31, no matter the diameter of fixing band 21
With the diameter of backer roll 31 how, the plus-pressure of backer roll 31 will not be all applied on heat transfer member 22.
Hereinafter, for fixing device 20 as constructed as above it is usual when action carry out simple illustration.
When the power switch input of image forming device body 1, electric power can be from being arranged on image forming device body 1
In power supply be supplied in heating tube 25, backer roll 31 also begins to rotate driving towards arrow B directions in Fig. 2.
In this way, by the rotation of backer roll 31, fixing band 21 between backer roll 31 and fixing band 21 also because occur
Frictional force and driven rotation on arrow A directions in fig. 2.
Be placed with the toner image T as unfixed image with paper P obtain guide plate guide while also Fig. 2's
Arrow C1 is transported on direction, and is admitted in the fixing nip portion N of the fixing band 21 in crimped status and backer roll 31.
Then, by the heat transfer member 22 that is heated from heating tube 25 come the heating of heated fixing band 21, and by increasing
Strong component 23 forms the pressing force of component 26 and backer roll 31 come the clamping that strengthens, and toner image T is just fixed to the table with paper P
On face.Afterwards, transported from what fixing nip portion N was sent out with paper P towards arrow C2 directions.
At this moment, due to the environmental condition residing for paper P species or state, machine, toner adhesion amount etc., have
Shi Houyong paper P can be easily sticked on fixing band 21.In this case, it is that will be taken up by separating plate 60 with paper P to use
What paper P was separated from fixing band 21 and transported towards arrow C2 directions.In this way, a series of fixing process in fixing device 20 obtains
To terminate.
It is the specific composition schematic diagram of in general separating plate 60 shown in Fig. 3.
Separating plate 60 is to be embedded into be arranged on the framework of fixing device 20 by the rotational axis hole 60a of separating plate 60
It can be rotated in rotary shaft.With to be used as the leading end portion 60c of separation unit by the use of paper P from the function that fixing band 21 separates
It is the end by paper orientation upstream side of separating plate 60, there is the gap less than 2mm to come between the surface of fixing band 21
It is opposite and right.In the long side direction both ends of separating plate 60, it is provided with for determining separating plate 60 relative to fixing band 21
Position and as the locating surface 60b of align member.Then, separating plate 60 is applied by torsion spring towards the side of fixing band 21
Power, and separating plate 60 is finally carried out relative to fixed by locating surface 60b and the abutting of the non-image areas on the surface of fixing band 21
The positioning of shadow bands 21.Locating surface 60b tip is bending, and the bearing surface of itself and fixing band 21 is smoothly formed.
In addition, because being the positioning that fixing band 21 and separating plate 60 are only carried out by separating plate, fixing band 21
Gap between separating plate 60 is easy for adjusting.As illustrated in fig. 2, be placed with toner image passes through fixing band 21 with paper P
Come after fusing toner what is gone out from fixing nip portion N.At this moment, it is generally desirable to firm by the curvature of fixing band 21 and with paper P
Property to be separated from fixing band 21 naturally with paper P.However, due to paper P hardness, humidity, the mounting situation of toner
, sometimes can be easily on fixing band 21 with paper P Deng a variety of causes.Separating plate 60 is to take up use by leading end portion 60c
After paper tip leaves the floating of the very little on the surface of fixing band 21, to cause what is separated with paper P from fixing band 21.
Further, leading end portion 60c can be arranged to contact with the surface of fixing band 21 or approach by separating plate 60.As from
In the Fig. 2 for the sectional view that long side direction is seen, although the leading end portion 60c of separating plate 60 appears to be what is connected with fixing band 21,
But it is to be provided between fixing belt surface and the leading end portion 60c of separating plate 60 less than 2mm at least in the range of with paper width
Gap.Because when the surface of fixing band 21 is damaged because of contact, can occur in the picture in toner fixing
The influence of scar, so being injured not because of separating plate 60 for the surface of fixing band 21.
Further, separating plate 60 is provided with opening portion 60e on separating plate long side direction (passing through paper width direction)
With penetrate and move it is opposite with paper P and to spigot surface 60d and it is opposite in spigot surface 60d opposite side and fixing band 21 and
To back side 60k (Fig. 5).Separating plate 60 shown in Fig. 3 has four opening portion 60e.
These opening portions 60e is for so that the hole that water vapour for being heated and being occurred with paper P etc. dissipates upward.No
During the 60e of opening portion, lose the water vapour back side 60k that passes through separating plate 60 in dissipation place to go etc. and condense and drip to fixing band 21
On, be further attached to after on paper P, will produce sometimes with paper P wrinkle or fold, the exception of pollution or toner image
Deng.
The oblique view for the separating plate 60 being provided in shown in Fig. 4 in the fixing device 20 involved by present embodiment, Fig. 5 institutes
Show the oblique view for the back side 60k for being separating plate 60.
As illustrated in fig. 4, in the part of the spigot surface 60d between the opening portion 60e that separating plate 60 abuts, formed with work
To install the rib mounting hole 60i of the installation portion of rib 61, the rib 61 is the guiding structure that can be arranged on separating plate 60
Part.To connect and be described below with Fig. 6,8,9 etc. for rib 61, in the state for being mounted with rib 61, rib 61 to
It is to be protruded from the spigot surface 60d of separating plate 60 vertical direction less.Rib mounting hole on the long side direction of separating plate 60
60i preferable allocation position is the width for avoiding the norminal size paper that fixing device and image processing system can use
The position that direction end is passed through.When with paper end by position and rib mounting hole 60i overlapping, with paper P width
End can be hooked into rib mounting hole 60i, so as to cause warpage or paperboard with paper P.
In addition, the rib mounting hole 60i's formed on separating plate 60 is provided with opening portion 60e between each other, it is penetrated
In with it is opposite with paper P and to spigot surface 60d and and fixing band 21 that spigot surface 60d is opposite side it is opposite and to the back side.
The separating plate 60 has six opening portion 60e on long side direction., would not be by setting opening portion 60e in separating plate 60
Condense in opening portion, and because the thermal capacity of separating plate 60 can also be reduced simultaneously, can just improve to condensation
Caused image problem prevents effect.
In addition, in the opening portion 60e of long side direction extension one side with paper conveyance direction upstream side, formed with from leading
The the first bending section 60f bent to the lateral fixing bands 21 of face 60d mono- and back side 60k (Fig. 5) side.Due to extending in long side direction
The first bending section 60f bear with paper come power, so just can be on separating plate long side direction at least first of separating plate 60
The intensity of end 60c sides is kept.Thus, compared with being not provided with the first bending section 60f situation, separation can be reduced
The thickness of plate 60, so as to further reduce the thermal capacity of separating plate 60.Thus, with being not provided with opening portion 60e or first
Bending section 60f situation is compared, and when starting heating tube 25 since low temperature environment to begin to warm up, enables to separating plate 60
Temperature rapid increase, it is thus possible to so that the water droplet occurred on separating plate 60 evaporates as early as possible.In addition, to fixing band 21 and the back side
First bending section 60f of 60k sides bending, which will not also be hindered, passes through paper.
In addition, long side direction extension opening portion 60e one side with paper conveyance direction downstream in, be also formed with from
The lateral fixing bands 21 of spigot surface 60d mono- and the second bending section 60g of back side 60k (Fig. 5) side bending.Thus, it becomes possible to enter one
The intensity of the long side direction of step enhancing separating plate 60.
However, the separating plate 60 that just input power supply has waited afterwards at low ambient temperatures begins to print when not being sufficiently heated
In the case of, even composition as described above can also condense on separating plate 60, and there may be image problem.In order to
Avoid this point, such as it is following as illustrated in fig. 6, can also be afterwards by rib according to on separating plate 60.
Fig. 6 is the oblique view of the separating plate 60 when being mounted with rib 61 in separating plate 60 shown in Fig. 4, and Fig. 7 is in Fig. 5 institutes
Show the oblique view of the separating plate 60 when rib 61 is mounted with separating plate 60.
Rib 61 can load and unload in the rib mounting hole 60i of separating plate 60, in the state of being installed in separating plate 60,
It is the linear component from the surface of separating plate 60 protrusion.Rib 61 linearly extends with paper conveyance direction.Passing through will
The rib 61 is installed to the surface of separating plate 60, is just lifted and is oriented to by rib 61 with paper P, thus can just reduce separating plate 60
Spigot surface 60d and the contact area with paper P.Therefore, there is condensation on the spigot surface 60d of separating plate 60, it is also difficult with paper P
To touch condensation, so as to suppress water droplet to the attachment with paper P.In addition, by the rib 61 of linear component, because energy
Enough shapes for reducing the rib mounting hole 60i formed on separating plate, rib is not set so can just reduce on separating plate
The generation with paper warpage or paperboard during bar 61 caused by the rib mounting hole 60i of (Fig. 4,5).
Further, the surface of the rib 61 with sliding movement with paper P image surface is preferably formed as acute angle or has R arcs
Degree.In this way, because the slide area of image surface and rib 61 further reduces, it becomes possible to reduce the rib vestige area on image
With sliding friction caused by image it is disorderly.
In addition, for material as rib 61, made with fluoroplast preferably.Due to fluoroplast be heat resistance compared with
Height, mobility or release property also good special material are slided, the rib 61 on the separating plate 60 in high temperature in fixing
Also it will not deform, and the accumulation of the foreign matters such as toner is less likely to occur.Therefore, it becomes possible to being carried out steadily in the long term with paper P
Pass through paper.
It is the oblique view of the shape of rib 61 shown in Fig. 8.
As shown in Fig. 8 (a), rib 61 has in the spigot surface 61e linearly to be extended with paper conveyance direction.It is being oriented to
Face 61e upstream side is formed with flat upstream-side-end 61a.In spigot surface 61e long side direction central portion formed with setting up separately
The locator protrusions 61b that fixed part 61d in spigot surface 61e left and right and the rear in spigot surface 61e protrude.Can by Fig. 8 (b)
Know, the contact surface with the spigot surface 60d of the separating plate 60 fixed part 61d contacted is composition that is flat and touching with spigot surface 60d.
By forming two fixed part 61d in spigot surface 61e left and right, rib 61 will be stablized, would not be shaken relative to separating plate 60
Shake.Spigot surface 61e downstream is to carry out shape as the end of downstream side 61c in the rib mounting hole 60i for fastening to separating plate 60
Into.When rib 61 is installed on separating plate 60 (Fig. 9), from upstream side towards downstream, spigot surface 61e is gradually from separation
The spigot surface 60d of plate 60 is elevated, and near the locator protrusions 61b there is identical height to end of downstream side 61c.More
Further, spigot surface 61e is all formed as acute angle over the entire length thereof, and its tip 61f turns into flat by chamfering.Therefore,
Due to smoothly being contacted with paper P with spigot surface 61e, easy damaged paper is not just allowed.
It is the side cross-sectional views for the separating plate 60 for being mounted with rib 61 shown in Fig. 9, is rib 61 shown in Figure 10 to separating plate
The schematic diagram of 60 installation steps.
As illustrated in fig. 9, the rib 61 respectively constituted with separating plate 60 is to be installed to be arranged on separating plate as shown in figure
In 60 spigot surface 60d rib mounting hole 60i.In the state for being mounted with rib 61, rib 61 is at least from separating plate 60
Spigot surface 60d vertical direction protrude.
Rib 61 is as follows to the installation steps of separating plate 60.
First, user holds the rib that the upstream-side-end 61a of rib 61 is inserted into upstream side by rib 61 (Figure 10 (a))
In bar mounting hole 60i (Figure 10 (b)).Then, user inserts the locator protrusions 61b of rib 61 the rib peace of the central portion of circular hole
Fill in the 60i of hole (Figure 10 (c)), is finally to install the rib in the end of downstream side 61c of rib 61 downstreams for being inserted into square hole
In the 60i of hole, and rib 61 is fixed on separating plate 60 (Figure 10 (d)) by end of downstream side 61c fastening.By using
Rib 61 can be just simply installed on separating plate 60 by the installation method of this manner, user afterwards.In this way, point
From plate 60 shape be just configured in the state of no rib 61 can without change by paper, meanwhile, be mounted with
Also paper can be passed through in the state of rib 61.Therefore, in the case of easily being condensed on separating plate 60, image shape is used
Rib 61 can be installed in fixing device 20 to prevent image problem by the user into device afterwards.In addition, do not needing
Consider condensation, more important is worry rib to during vestige, rib 61 can be installed to separation by user caused by image
Image processing system is used in the case of on plate 60 without change.In this way, because only providing rib 61 to necessary user,
Compared with carrying the situation of rib in advance in all fixing devices, it becomes possible to reduce the average unit cost of fixing device.
It is the plan for the separating plate 60 for being mounted with rib 61 shown in Figure 11.
As illustrated, rib 61 is protruded from the spigot surface 60d of separating plate 60.Moved with being slided with paper P image surface
The surface (spigot surface 61e) of rib 61 be formed as acute angle or there is R (radian).Fixed part 61d and separating plate 60 spigot surface 60d
Contiguity, and rib 61 will not rock relative to separating plate 60.
It is the oblique view of the variation of rib 61 shown in Figure 12.
The rib 61 is on the composition of the rib shown in Fig. 8, also between upstream-side-end 61a and fixed part 61d
There is provided the roller 61g that can be rotated around axle 61h.Axle 61h protrudes from spigot surface 61e both sides towards side, roller 61g
It is arranged on axle 61h with will not fall off.Because roller 61g protrudes than spigot surface 61e more upward, pass through leading end portion 60c
And would not be slided with spigot surface 61e mobile with paper P from the separation of the surface of fixing band 21 or be only that slip slightly is moved, and lead to
Roller 61g is crossed to be directed to towards downstream.It is tool that is, in the state of rib 61 is installed on separating plate 60
Have from the surface of separating plate 60 protrusion and as the roller 61g of roller component.Therefore, compared with as the rib of linear component,
Injury is more difficult to paper, is just difficult to occur the problem of sliding friction vestige and image.
In addition, and be formed as acute angle with the mobile roller 61g surfaces of paper P image surface slip or there is R radians.In this way,
Because image surface and roller 61g slip migration area further reduce, it becomes possible to reduce the area of the rib vestige on image
With sliding friction caused by image it is disorderly.
In addition, for material as roller 61g, made with fluoroplast preferably.Because fluoroplast is heat resistance
It is higher, mobility or release property also good special material are slided, the upper roller of separating plate 60 of high temperature is in fixing
61g will not also be deformed, and the accumulation of the foreign matters such as toner is less likely to occur.Therefore, it becomes possible to being carried out steadily in the long term with paper P
Pass through paper.
Further, roller 61g radius is larger, before rib 61 and separating plate 60 fasten locking, in order to not cause roller
61g contacts with separating plate 60, it is therefore necessary to increase corresponding to upstream-side-end 61a rib mounting hole 60i transverse width or
It is longitudinally wide.
The long side direction end for the separating plate 60 being provided in shown in Figure 13 in the fixing device 20 involved by present embodiment
The part oblique view in portion.
The rotational axis hole 60a of separating plate 60 is embedded in the rotary shaft 63 on the framework 62 for being arranged on fixing device 20,
And it can be rotated together with rotary shaft 63.In this way, separating plate 60 is just fixed on fixing device side.Therefore, user is with regard to energy
It is enough that separating plate 60 is installed on fixing device come oneself according to use environment, or removed from fixing device.Rotary shaft
63 extend since framework 62 towards direction of principal axis inner side.The locating surface 60b of separating plate 60 in non-image areas with fixing band 21
Surface abut, thus allow for separating plate 60 and be positioned relative to fixing band 21.That is, separating plate 60 is relative to fixed
Shadow bands 21 have locating surface 60b.As it was previously stated, locating surface 60b tip is bending, it is smooth with the bearing surface of fixing band 21
Ground is formed.
As described above, in the present invention, the rib mounting hole 60i of the ways of the grade of rib 61 on separating plate 60 by with
Being set to will not hinder with the conveyance of paper, also, user can install ways as needed.Can be in fixing dress
Do not installed in putting in the case of ways to pass through paper by paper or being mounted with the state of ways
.Used under high humility and low temperature environment, or printing etc. at once is more easy after recovering since the state of cooling to not machine
In the case of being condensed in separating plate 60, user can be directed to component and be installed on separating plate to prevent image problem.
In turn, without the concern for condensation, more important is the weight for worrying roller vestige caused by ways or rib vestige etc.
The user of visible image quality, ways can not be installed and use fixing device without change.
