On the other hand, Fig. 2 has shown system as the apparatus structure pattern, and this figure has shown that for convenience's sake the system of using Yellow toner among Fig. 1 is as device 21Y.
System is relevant as having multiple arrangement and image to form among the device 21Y.Wherein, except writing station and transfer printing portion, photosensitive drums 25Y, photosensitive drums is carried out image form the charging device 27Y that handles, the electrostatic latent image after writing is made the developing apparatus 26Y of visualization processing and removed toner on the photosensitive drums of staying after the transfer printing and the cleaning device 28Y (among Fig. 2 cleaning balde being labeled as 28Y for convenience's sake) of foreign matter such as paper powder is collected among the handle box 21PC together.
Be concealed among the handle box 21PC and form relevant above-mentioned a plurality of parts and device with image, its life-span has nothing in common with each other.Wherein, developing apparatus 26Y is long than the photosensitive drums 25Y life-span, and when photosensitive drums 25Y reaches exchange during period, developing apparatus 26Y can also continue to use.
A plurality of parts or device that present embodiment forms for relevant image in handle box or the handle box, to wherein replace original parts or device than miscellaneous part or device lifetime than long parts or device relatively, other image processing systems of packing into utilize again, to save resource.
Present embodiment uses developing apparatus 26Y as utilizing object again.
Among Fig. 2, developing apparatus 26Y use to mix two composition developers of toner and carrier, and it comprises: the developer mounting body in the face of photosensitive drums is development sleeve 26A, mixes and the supply of developer sleeve 26B is provided and stirs sleeve 26C, be positioned at the additional toner input material 26D of portion that stirs sleeve 26C top, place near the magnetoconductivity sensor 26S that is used for conduct detection concentration of developer device the stirring sleeve 26C on one side.
Among the developing apparatus 26Y, magnetoconductivity sensor 26S is the impedance of object detection developer with the developer, calculates the mixture ratio of carrier and toner, and according to the result of the ratio that relatively this mixture ratio is corresponding with normal concentration, the control toner replenishes.
When magnetoconductivity sensor 26S detects toner concentration, carry out initialization process with correction error.That is to say that the sensitivity deviation of sensor itself and the developer storing portion deviation in structure or assembling can make the difference that produces flowing property and volume density between the developer, this difference can cause the detection error.For this reason, carry out toner concentration output voltage treatment for correcting, proofread and correct control voltage with developer, so that the magnetoconductivity sensor output voltage becomes setting with benchmark concentration.The developer that use this moment is original new reagent.
In image processing system, the developing apparatus that uses with present stage is object, carries out initialization process according to the initial information of wherein magnetoconductivity sensor, carries out concentration of developer management control.Yet, as mentioned above, because developing apparatus is that the photoreceptor 25Y life-span is long than the device that other the relevant images in the handle box form, and can keep this developing apparatus when calcellation handle box or photoreceptor, and utilize as the developing apparatus in other image processing system handle boxes again.
But, will be once when used developing apparatus is used as original developing apparatus and is used for image processing system in other image processing system, can take place to use the initial information that is used for concentration of developer control in the relevant former image processing system that is retained in wherein, if promptly the relevant initial information to the magnetoconductivity sensor does not make any changes, then it can't be used as the concentration of developer control information in other image processing systems.
This is because the carrier characteristics of developer has nothing in common with each other in the image processing system, perhaps because two composition concentration of developer promptly is used for detecting the magnetoconductivity sensor output voltage of carrier toner concentration and the relation between the toner concentration has nothing in common with each other, moreover might be because the linear speed form that adopts is inequality or the like in the image processing system, had better not be used for other image processing systems with being in magnetoconductivity sensor sensitivity information in the developing apparatus of operational phase etc.And, initialization process is the processing of carrying out at new developer, and to re-using the developing apparatus in other image processing systems, the developer of wherein depositing is through using, it or not original new developer, therefore, having taken place to carry out with the magnetoconductivity sensor in the developing apparatus of depositing new developer is the initialization process that object was carried out.
Form about linear speed, if the image processing system that adopts the operational phase developing apparatus is with identical as the image processing system condition of not using the developing apparatus use with the operational phase developing apparatus, can be in use makes the operational phase developing apparatus do not make any changes about the output voltage of linear speed and the relation between this output voltage and the concentration.But in fact image processing system has nothing in common with each other on specification, therefore, as mentioned above, is difficult to without the information of changing in the ground use operational phase developing apparatus.Fig. 3 has shown the relation between linear speed and the output voltage.From this figure as can be known, sensor output is tended to diminish when linear speed accelerates, even adjust control voltage, the sensor initial information also can can't be used because of linear speed in the image processing system has nothing in common with each other.
To this, present embodiment is to the initial information in the operational phase developing apparatus, especially the initial information in the magnetoconductivity sensor, that is: the output valve (Vt) when being used for magnetoconductivity sensor initializing that concentration detects, control voltage (Vtcnt), export target value (Vtref), developing property (γ), processing linear speed value during initial treatment, temperature during initial treatment, various initial informations such as humidity, at least a information wherein is kept at the operational phase developing apparatus or comprises in the handle box of this developing apparatus, when this developing apparatus is used as it untapped developing apparatus and is utilized by other image processing systems, these other image processing systems read this preservation information, again this developing apparatus is carried out initialization process, perhaps form the concentration of developer management control that is applicable to other image processing systems according to initial information.
