Fixing device 300 is that feeding sheets adopts heat to make developer as the device of photographic fixing at sheet material on one side on one side, and this device is used as sending the heating part of heat.In addition, fixing device 300 possess warm-up mill 302 with hollow bulb and with the backer roll 304 of warm-up mill 302 crimping.Warm-up mill 302 is accepted to rotate to the direction of arrow shown in Figure 1 from the driving transmission of aftermentioned motor 420, and backer roll 304 is driven in warm-up mill 302 to direction of arrow rotation shown in Figure 1.In the hollow bulb of warm-up mill 302, dispose the well heater 310 that uses as thermal source.
Fixing device 300 comes feeding sheets in the mode of utilizing warm-up mill 302 and backer roll 304 to clamp, with the part that backer roll 304 contacts sheet material is heated pressurization at warm-up mill 302, makes developer as photographic fixing at sheet material thus.
In addition, image processing system 10 has the motor 420 that is used as drive source.Motor 420 is via linking such as the drive transmission mechanism 430 that is made of gear row etc. and outlet roller 204, registration roller 402, photoreceptor 110, warm-up mill 302 and distributing roller 404.Make outlet roller 204, registration roller 402, photoreceptor 110, warm-up mill 302 and distributing roller 404 rotations come feeding sheets by the driving of transmitting from motor 420.In addition, can come by the rotational speed of control motor 420 the sheet material transporting velocities such as speed of control example such as fixing device 300 feeding sheets.
In addition, control circuit 502 with link such as the memory storage 520 that is consisted of by nonvolatile memory chip etc.
Memory storage 520 uses as storage unit, and this cell stores has the temperature of the fixing device 300 that temperature sensor 330 detects and the temperature of the fixing device cap 18 predicted.
Fig. 3 is the 1st process flow diagram of action of the image processing system 10 of explanation the 1st embodiment.
As shown in Figure 3, when a succession of action of beginning, in initial step S10, control device 500 comes predicted picture to form the temperature of the fixing device cap 18 of apparatus main body 12 according to the temperature of the fixing device 300 that temperature sensor 330 detects with the temperature that is provided with the environment of image processing system 10.
When the temperature that is provided with the environment of image processing system 10 when employing is predicted the temperature of fixing device cap 18, for example can adopt the environment maximum temperature of the action that can guarantee image processing system 10 to be used as being provided with the temperature of the environment of image processing system 10.In addition, can adopt near the temperature the transfer device 130 that the resistance change brought according to the temperature of the transfer roll that consists of transfer device 130 predicts, as the temperature of the environment that is provided with image processing system 10.In addition, in the situation that environment temperature sensor 540 is installed, the temperature that environment temperature sensor 540 can be detected is used as the temperature of the environment that is provided with image processing system 10.
In step S10, the heat that control device 500 supposition is proportional from the temperature difference that fixing device 300 flows into the heat of fixing device caps 18 and fixing device 300 and fixing device cap 18, go out from fixing device cap 18 outside air-flows and fixing device cap 18 and outer temperature degree are proportional, predict the temperature of fixing device cap 18.Namely, be made as Tc1 when the predicted temperature with fixing device cap 18 is made as Tc, the temperature that the firm prediction of fixing device cap 18 is complete, the temperature of the warm-up mill 302 measured is made as Tr, will be provided with image processing system 10 environment temperature namely outside the temperature degree be made as Tair, when h1, h2 are made as proportionality constant respectively, control device 500 is predicted the temperature of fixing device cap 18 according to following formula.
Tc=Tc1+h1X(Tr-Tc1)-h2×(Tc1-Tair)
Here, suitably adopt after changing value as h1, the h2 of proportionality constant such as carrying out image formation etc. according to the transporting velocity of sheet material, the size of sheet material that forms image or no moment in prediction.
In next step S12, whether control device 500 is differentiated the fixing device cap 18 of the image processing system main body 12 of predicting in step S10 temperature surpasses predetermined set point of temperature.Here, consider the whether exposed to contact position of operator etc. of the material of image processing system main body 12 or fixing device cap 18, decide predetermined temperature.When in this step S12, differentiating temperature for fixing device cap 18 and surpass predetermined set point of temperature, enter step S20, when differentiating when not have above the set point of temperature of being scheduled to for the temperature of fixing device cap 18, enter step S30.
In step S20, control device 500 reduces the temperature of fixing device 300 by control heater 310.
In next step S22, for example in step S20, reduce in the temperature of fixing device 300, control motor 420 reduces the speed of fixing device 300 feeding sheets.In this step S22, because reduce the speed of fixing device 300 feeding sheets, so compare with the situation of the speed that does not reduce sheet material, the heat that the per unit area of sheet material is supplied with increases.Therefore, even in step S20, reduce the temperature of well heater 310, also be difficult to produce owing to the not enough photographic fixing of developer picture on sheet material that causes of heat is bad.
In next step S30, control device 500 control image forming parts 100 make image forming part 100 form the developer picture.The developer picture that is formed by image forming part 100 is transferred on the sheet material by transfer device 130, and is fixed on the sheet material by fixing device 300.Then, will the sheet material after the toner image photographic fixing be discharged to discharge portion 16 via distributing roller 404 by fixing device 300.
In next step S40, control device 500 is according to differentiate the whether processing relevant with last view data of a succession of processing via the view data of communication interface 504 inputs, if differentiate for being last view data then entering step S100, if differentiate for being not last view data then returning step S10.
In step S100, control device 500 makes the temperature of the fixing device 300 that memory storage 520 storage measured by temperature sensor 330 and in the temperature of the fixing device cap 18 of the image processing system main body 12 of step S10 prediction under rated condition.
Like this, in image processing system 10, do not make memory storage 520 storage data during the image in forming step S30, do not form image during make memory storage 520 storage data.Therefore, the electric noise that forms of the such accompanying image of direct motor drive or high-voltage power supply does not have subtend memory storage data writing to bring baneful influence.
Fig. 4 is the 2nd process flow diagram of action of the image processing system 10 of explanation the 1st embodiment, is the process flow diagram that the details of step S100 shown in Figure 3 is shown.
As shown in Figure 4, when beginning step S100, control device 500 is differentiated in step S102 below the limit temperature whether temperature of the fixing device cap 18 of the image processing system main body 12 of predicting in step S10 be scheduled to.Then, when the temperature of the fixing device cap 18 of prediction during greater than predetermined limit temperature, control device 500 makes the temperature of the fixing device cap 18 of the temperature of the fixing device 300 that memory storage 520 storages measure and prediction.
On the other hand, the limit temperature be scheduled to when following in the temperature of fixing device cap 18 of prediction, control device 500 do not make the temperature of the fixing device 300 that memory storage 520 storages measure and prediction fixing device cap 18 temperature data and finish a series of processing.Like this, limit the situation that the temperature of the fixing device cap 18 of the temperature of the fixing device 300 that will measure and prediction is stored to memory storage 520 again according to temperature, so can suppress owing to the memory storage 520 that repeatedly causes to memory storage 520 storage data is deteriorated.
After after becoming the state of cutting off the electricity supply, reclosing power supply, for predicted picture forms the temperature of the fixing device cap 18 of apparatus main body 12, and adopt the temperature of the fixing device cap 18 of the mensuration temperature of the fixing device 300 that memory storage 520 records in step S104 and prediction.Namely, reclose power supply after becoming the state of cutting off the electricity supply after, the temperature of the fixing device 300 that control device 500 employing memory storages 520 are stored and the predicted temperature of the fixing device cap 18 that memory storage 520 is stored are predicted the temperature of fixing device cap 18.
As mentioned above, in step S10, in order to predict the temperature of fixing device cap 18, be Tc1 and adopt the temperature of the fixing device cap 18 of just having predicted.Because temperature sensor 330 can't be measured the temperature of fixing device 300, be Tc1 so there is not the temperature of the fixing device cap 18 of just having predicted under this state of after plugged, cutting off the electricity supply.Therefore, after plugged, the mensuration temperature of the fixing device 300 that control device 500 employing memory storages 520 are stored and the predicted temperature of the fixing device cap 18 that memory storage 520 is stored are predicted the temperature of fixing device cap 18.
At this moment, suppose that fixing device 300 is identical with respect to the ratio that environment temperature reduces with the temperature of fixing device cap 18 with respect to the ratio that environment temperature reduces during cutting off the electricity supply, the temperature of control device 500 prediction fixing device caps 18.Namely, when predicted temperature that the predicted temperature with fixing device cap 18 is made as the fixing device cap 18 that Tc, memory storage 520 store be made as Tc2, will be provided with image processing system 10 environment temperature namely outside the temperature of the temperature degree fixing device that is made as Tair, will be made as in the temperature of the fixing device of the chronometry of plugged Tr, memory storage 520 is stored when being made as Tr2, control device 500 is predicted the temperature of fixing device cap 18 according to following formula.
Tc=(Tc2-Tair)×[(Tr-Tair)/(Tr2-Tair)]
Here, can apply the temperature that fixing device cap 18 is predicted in certain correction to the temperature of utilizing the following formula prediction.That is, when corrected value is made as A, can predict according to following formula the temperature of fixing device cap 18.
Tc=(Tc2-Tair)×[(Tr-Tair)/(Tr2-Tair)]+A
Here, because the temperature difference of fixing device 300 and environment temperature is greater than the temperature difference of fixing device cap 18 with environment temperature, so corrected value A is the situation of the speed of considering that speed that the temperature of fixing device 300 reduces reduces greater than the temperature of fixing device cap 18 and definite value.
The image processing system 10 of the 1st embodiment described above, image at step S30 forms in the action as shown in Figure 3, do not make the predicted temperature of memory storage 520 storage fixing device caps 18 etc., after image forms end, in step S100, make the predicted temperature of memory storage 520 storage fixing device caps 18 etc.Therefore, when the image at step S30 forms the situation that middle generation cuts off the electricity supply, after the predicted temperature of the fixing device cap 18 of having stored memory storage 520 storages, even the predicted temperature of fixing device cap 18 rises, do not make the temperature of the fixing device cap 18 of memory storage 520 these risings of storage yet.
Therefore, when the image at step S30 formed the situation that middle generation cuts off the electricity supply, when plugged, the predicted temperature that was stored in the fixing device cap 18 in the memory storage 520 before adopting was predicted the temperature of fixing device cap 18.Therefore, although should reduce fixing device 300 temperature, reduce the sheet material transporting velocity of fixing device 300, sometimes do not carry out the control of the reduction sheet material transporting velocity of the control of temperature of reduction fixing device 300 of control device 500 and fixing device 300.Therefore, in order to suppress the generation of these drawbacks, can with the temperature of reference temperature (threshold value) the equal extent predicted temperature as fixing device cap 18, store memory storage 520 into, then carrying out image forms, wherein, reference temperature is the benchmark that reduces the temperature of fixing device 300, reduces the sheet material transporting velocity of fixing device 300.In addition, the higher grade of problem when wishing to set for parts (being the photographic fixing cap) as object here and surpassing threshold value, and the temperature that this memory storage 520 is stored is lower.
In addition, in the image processing system 10 of the 1st embodiment described above, when differentiating temperature for the fixing device cap 18 predicted at step S12 and surpass predetermined set point of temperature, in step S20, reduce the temperature of fixing device 300, and reduce the speed of fixing device feeding sheets in step S22, the image that then carries out image forming part 100 forms.Replace this control or therewith control when differentiating temperature for the fixing device cap 18 predicted at step S12 and surpass predetermined set point of temperature, forbid the control that the image of image forming part 100 forms in the lump.
When the image that stops image processing system 10 forms, for example during the predetermined stipulated time, can stop image and form the control that then restarts image formation.In addition for example, can stop image formation until the temperature of fixing device 300 becomes the control that below the predetermined set point of temperature, then restarts image formation.In addition for example, can stop image formation until the predicted temperature of fixing device cap 18 becomes the control that predetermined set point of temperature is following and then the beginning image forms.
In addition, above explanation is to form lid temperature in the action as prerequisite take predicted picture, but except image forms action, must be lower with the Temperature Setting of fixing device 300 and as the action so-called for subsequent use of the state that forms action in order to image in or in action beyond it, wishes all to predict at any time that photographic fixing section covers temperature.
In addition, example as follows has been described: the fixing device cap 18 of image processing system main body 12 is used as the section that is heated, when the temperature of the fixing device cap 18 of predicting surpasses predetermined set point of temperature, reduces the control of the temperature of fixing device 300 in the image processing system 10 of the 1st embodiment described above.In this point, can replace fixing device cap 18 as being heated section, for example can be with developing apparatus 120 or cleaning device 140 as being heated section.Namely, for example predict the temperature of developing apparatus 120 or cleaning device 140 according to the output of the output of temperature sensor 330 or environment temperature and temperature sensor 330, when the temperature of this prediction is the set point of temperature of being scheduled to, can reduce the control of the temperature of fixing device 300.
Fig. 5 is the curve map of an example of action that the image processing system 10 of the 1st embodiment is shown.In Fig. 5, the temperature and time that line a illustrates fixing device 300 changes accordingly.The temperature of the fixing device 300 shown in the line a can utilize temperature sensor 330 to measure, and perhaps adopts the photographic fixing section of installing in addition in order to measure to measure with temperature sensor (not shown).But, when cutting off the power supply of image processing system 10, can't carry out the mensuration of temperature sensor 330, so adopt photographic fixing section to measure the temperature of fixing device 300 with temperature sensor.
In addition, in Fig. 5, line b illustrates the temperature of the fixing device cap 18 of image processing system main body 12.The temperature of fixing device cap 18 adopts the main body of installing in addition in order to measure to measure with temperature sensor (not shown).In addition, in Fig. 5, line c illustrates the temperature of the fixing device cap 18 that the temperature that adopts fixing device 300 and environment temperature predicted by control device 500.In addition, in Fig. 5, the sheet material transporting velocity when line d illustrates fixing device 300 feeding sheets.
In addition, the time period A among Fig. 5 and time period C are the time periods of cutting off the electricity supply after carrying out image formation to image processing system 10 pluggeds.In addition, time period B be after cutting off the electricity supply the time period before the then plugged.In addition, time period D is the time period that forms in time period C after image is cut off the electricity supply afterwards.
In Fig. 5, as can be known, in time period A and time period C, the temperature of the fixing device cap 18 that is doped by control device 500 and main body approach with the temperature of the fixing device cap 18 that temperature sensor is measured when alternative line c and line b.
