Be installed in the upper end of vertical next door part 66g to plate 90.The front end of scraper plate 90 contacts with the position slightly backward, top of magnetic roller 88 left magnetic rollers 88.Developer be thus lifted to magnetic roller 88 on the rear flank because to the effect of plate 90, developer is provided to the transmission spiral 78a of developer mixing part 76.
Generally speaking, the developer that leaves in the developer storage case 66 is transported to developer storage compartment 70 from developer mixing part 76 through developer spillway 66h and passage 82; Then developer roll 68 is delivered to the district of developing with developer from developer storage compartment 70; Developer is promoted by magnetic roller 86,88 continuously by the back, district of developing; At last, developer turns back to developer mixing part 76 through scraper plate 90.Like this, when developing apparatus 54 work, developer is circulation continuously in developer storage case 66.Because this can guarantee constantly to be offered developer storage compartment 70 by well-beaten developer (that is, in the developer that provides, toner and magnetic carrier component are by frictional electrification, and the toner component is evenly distributed in the magnetic carrier component).
The architectural feature of above-mentioned developing apparatus 54 is: developer storage case 66 is divided into developer storage compartment 70 and developer mixing part 76; The developer mixing part 76 that volume is bigger is arranged on the top of developer storage compartment 70.According to the structure of above developer storage case 66, can reduce the volume of developer storage compartment 70 widely.In this respect, as previously mentioned, because laser scanner 52 is the assemblies that constitute the maximum in the electrostatic recording apparatus assembly, therefore, it is set at the uppermost position in fig-ure of electrostatic recording apparatus.Yet, be equipped with the enough big space of the developer mixing part 76 of a receiving photographic developer reservoir vessel 66 at the upper of this electrostatic recording apparatus.Because this cause, even developer mixing part 76 is arranged on the top of developer storage compartment 70, also can not increase the size of electrostatic recording apparatus itself.
Specify the structure of cleaning device 60 below.Cleaning device 60 comprises: the toner returnable 60a with open section of a part of holding photosensitive drums 48; A hairbrush 60b who is located among the toner returnable 60a makes the opening portion setting of hairbrush 60b near toner returnable 60a; A toner that is provided with along the upper limb of the opening of toner returnable 60a is to plate 60c; With a conveyor screw 60d who is located at toner returnable 60a bottom.In this structure, hairbrush 60b brushes the residual toner on photosensitive drums 48 surfaces, and the residual toner that scraper plate 60c can not be brushed by hairbrush 60b is to removing.Residual toner by hairbrush 60b and scraper plate 60c removal temporarily is recovered among the toner returnable 60a.Toner conveyor screw 60d delivers to predetermined place with the toner that reclaims from toner returnable 60a.
In the above-described embodiments, as two magnetic rollers 68,88 of developer lifting gear developer is promoted from developer roll 68, so that developer is recovered to developer mixing part 76.But much less, also available single magnetic roller or use the magnetic roller be no less than 3 to make the developer lifting gear where necessary.
The developer wheel send device
Fig. 3 (a) and 3 (b) are the views of expression developer carrying device.Fig. 3 (a) is the top view of developer carrying device, and Fig. 3 (b) is the front view of developer carrying device.Fig. 4 is the view of expression developing apparatus 54 and developer carrying device 64.
Toner leaves in the toner Cartridge 642.When toner concentration in the developing apparatus 54 descended, toner was sent to developing apparatus 54 from toner Cartridge 642.In developer box 649, there are the toner of formation developer and the potpourri of carrier.When the developer in the needs replacing developing apparatus 54, developer is delivered to developing apparatus 54 from developer box 649.
A conveyor screw 78a who developer is delivered to developing apparatus 54 is set.Conveyor screw 78a is longer than developer roll 68.Developer carrying device 64 is connected to the part of conveyor screw 78a, because conveyor screw 78a is longer than developer roll 68, so the relative developer roll 68 of this part protrudes.
Carry by conveyor screw 78a from the developer that developer carrying device 64 is carried.Because aforesaid transfer movement, all the developer of amount is sent to developer roll 68 substantially.Thereby, on developer roll 68, can form the upright developer of even height.
In the developer box 649 of developer carrying device 64, be provided with a residue developer detecting sensor 657.Residue developer detecting sensor 657 detects the amount of residue developer in the developer box 649.The amount of the developer in leaving developer box 649 in substantially with leave developing apparatus 54 in the amount of developer when identical, when maybe the amount of the developer in leaving developer box 649 in is slightly smaller than the amount that leaves the developer in the developing apparatus 54 in, in other words, when the amount of the developer in leaving developer box 649 in can be sent into developing apparatus by a conveying operations, just do not need to use this residue developer detecting sensor 657.But, the amount of the developer in leaving developer box 649 in is when leaving the several times of developer level in the developing apparatus 54 in, for example, the amount of developer is when leaving the twice of developer level in the developing apparatus 54 in leaving developer box 649 in, just needs to detect the amount that remains in developer in the developer box 649.The surplus surplus developer detecting sensor 657 of condition must be set in this case.In the color printer that four developing apparatuss 54 are housed shown in Figure 1, usually printing is performed such, promptly deposit Huang, magenta, green grass or young crops and black four look developers and by this four looks developer with corresponding developable latent image, then the coloured image that develops is transferred on the paper.In these four kinds of colors, black uses at most.Therefore the capacity of other color developers box 649 of volume ratio of developer box 649 of depositing black reagent is big.For example, when the capacity of each developer box 649 of Huang, magenta, green grass or young crops and black reagent deposited is substantially identical with the capacity of developing apparatus 54, then can be once with the developer in the replacing of the developer in each Huang, magenta, green grass or young crops and the black reagent box 649 developing apparatus 54, and the capacity of black reagent box is when being the twice of developing apparatus 54 capacity, and then the black reagent that can be stored in developer box of the black reagent in the developing apparatus 54 is changed twice.Therefore, the replacing number of times of every kind of color developers is basic identical.When the capacity of developer box 649 was too big, the size of equipment will too increase, and was stored in that developer in the developer box can absorb airborne moisture and fixed.For avoiding above-mentioned defective, should make the capacity of black reagent box 649 equal the twice of developing apparatus 54 capacity, and the capacity of other color developers box 649 equate with the capacity of developing apparatus 54.
The operator changes developer by hand.
Change the transfer movement that program flow diagram illustrates developer according to Fig. 5 and developer shown in Figure 6 below.Fig. 8 is the view of a guidance panel.Guidance panel 810 comprises: display part 811 and a key definition 814 of being used for display message 813; Indication button 812, it is a kind of button, is used to indicate the key definition of giving key definition 814.Guidance panel 810 is installed in the position that is suitable for operator's operation on the color electrostatic recording apparatus shell.
In this color electrostatic recording apparatus, when counting the number of revolutions of developer roll 68, the time of changing developer in the developing apparatus 54 is detected.
When the revolution of developer roll 68 reaches when printing the predetermined number of revolutions of 150,000 pages of paper correspondences, developer is promptly near its life-span and need to prepare to change this developer.For making the operator notice the needs of changing developer, this information is displayed on information display section and divides 811 (steps 51). Magnetic roller 86,88 and developer mixing part 76 are driven along with the rotation of developer roll 68.Because developer is circulation constantly in developer storage case 66, stress is added on the developer, makes the developer quality descend.The result causes developer not charge and then can not be used for developing.For preventing that the problems referred to above from taking place, after changing developer, the mode of number developer roll 68 revolutions of using tricks detects the life-span of developer, with the quality decline of this revolution value estimation developer.The detection method in this developer life-span can be obtained by experiment.Since other parts of magnetic roller 86 and supplying developing agent with developer roll 68 by driven in synchronism, so only count the revolution of developer roll here, but also can be by counting magnetic roller 86, the revolution of magnetic roller 88 or developer mixing part 76 is differentiated the life-span of developer.
When printed information just in time occurs simultaneously with the demonstration of developer end-of-life, print operation and proceed.
When the operator does not change the developer that arrives the life-span and when continuing to print, to print operation and make and can not carry out normally, equipment is stopped operation (step 53).When developer roll 68 with predetermined number of revolutions rotation and reach with this near the life-span behind the corresponding revolution, operation of equipment is stopped.On the other hand, when preestablishing near two corresponding count values of life-span and equipment downtime with this, and the revolution of developer roll 68 is when reaching this analog value, and this equipment can be stopped.
Express " you think arrestment and change developer? " information be presented on the display part 811 (step 54).
When the indication button 812 of developer is changed in indication on operator's push panel 810 of color electrostatic recording and equipment, check at first whether developer (step 55) is arranged in the developer box 649.In checking developer box 649, during the existing of developer, use an optical sensor (not shown) that is located in the developer box 649 to check.In the essentially identical equipment of capacity of the capacity of developer box 649 and developing apparatus, check in the developer box 649 whether developer is arranged.At the capacity of developer box 649 is in the equipment of integer letter of developing apparatus 54 capacity, and whether the amount that is stored in developer in the developer box 649 with this light sensors is greater than the capacity of developing apparatus 54.
The amount of the developer in being stored in developer box 649 informs that the operator needs the information of supplying developing agent to be presented at the display part (step 56) of guidance panel 810 during less than the capacity of developing apparatus 54.Thereafter, this equipment enters waiting status and is admitted to until the developer of aequum.
The operator developer is added from developer the inlet 648 add developer box 649 after, push the indication button 812 of definition " affirmation ".When detecting this pressing operation of indication button 812 (step 57), the amount of developer detected once more (step 58) in the developer box 649.
The detection of developer level shows in to developer box 649, and when inadequate, in step 56, the information that requires the operator to add developer is presented at display part 811 once more concerning the amount of developing apparatus 54 developers.
When the detection in step 55 or 58 shows that concerning the amount of developing apparatus 54 developers developer is discharged from from developing apparatus 54 when sufficient.This discharge campaign will be described hereinafter.
In the operation that this developer is discharged, inform that the information that operator's developer is discharged shows (step 59) on display part 811.
After developer was all discharged from developing apparatus 54, the developer filler cap 653 tegmentum motors 651 of developer box 649 were opened, so that the developer in the developer box 649 adds developing apparatus 54 (step 510).In this operating period, inform that the information that operator's developer is added into shows on display part 811.
When developer filler cap 653 was opened, developer fell into developing apparatus 54 from developer box 649.Developer is transferred spiral 78 and sends into this developing apparatus then.
After developer was admitted to developing apparatus 54, the developer mixing part that is used to stir developer was driven, so that developer is charged.In this course, developer is prepared to deliver to photosensitive drums 48 by developer roll 68.
After developer was delivered to developing apparatus 54, developer filler cap 653 tegmentum motors 651 cut out.Cover sensor 652 detects the position of developer filler cap 653.Afterwards, in developing apparatus 54, insert concentration of developer deboost (step 513).When this was inserted, owing to use the concentration of toner in the light sensors developing apparatus 54, the light sensors part can be stained with toner, and therefore the amount of radiative amount or reception light can reduce.Because the toner concentration of the developer when being added into developing apparatus 54 is adjusted when putting on market rightly, therefore the toner concentration of the developer when detection is added into can obtain the adequate value of toner concentration.When this value when too low, the light quantity of optical sensor emission side increases, or the signal of light-receiving side obviously strengthens, and so just can detect toner concentration in normal running.Like this, toner concentration can be detected more rightly and be adjusted.
After developer in developer box 649 is sent into developing apparatus 54, form a space in the developer box 649.Thereby relatively large developer can leave in this space of developer box 649.Like this, inform that the information that the operator needs to send into developer to developer box 649 shows (step 514) on display part 811.
According to this information, the operator sends developer into developer box 649, and the key definition of guidance panel 810 detects, the indication button that the agent of indication supplying developing is finished whether be pressed (step 515).
Detect the amount of developer in the developer box 649, and the amount of developer is sufficient (steps 516) to sending into developing apparatus 54 in the detection developer box 649.Afterwards, equipment enters and waits the waiting state of printing operation.
When the operator manually sent developer into developing apparatus and developer box, this developer was stored at developing apparatus and the developer box that is used for changing developer.The amount of developer of the twice of suitable use amount promptly is provided.Therefore, during near its life-span, need manually change corresponding to the developer of use amount twice when this by the operator.In order to prolong the interval of changing developer, can leave the amount of the developer in the developer box in the integral multiple increase of developing apparatus capacity.
Automatically change developer
When the developer in the developing apparatus 54 during near its life-span, need with this developer from developing apparatus 54 discharge and be stored in the developer box 649 the developer replacing it.
When developer roll 68 with developing apparatus 54 in the toner of developer when delivering to photosensitive drums 48, the image on the photosensitive drums 48 is developed, the image of development is transferred on the transfer paper.Like this, the amount of toner is reduced in the developing apparatus 54.Be installed in the developing apparatus 54, the optical sensor (not shown) that is used for detecting toner concentration detects the concentration of developing apparatus 54 toners.When the toner concentration of developer reduced to the numerical value that is lower than predetermined value in being stored in developing apparatus 54, toner was admitted to from toner Cartridge 642.
For toner is delivered to developing apparatus 54 from toner Cartridge 642, toner carries motor 647 to be driven, and makes 650 rotations of toner conveyor screw.Because aforesaid operations, toner is sent to right side among Fig. 4.Fallen conveyor screw 78 through toner carrying roller 655 from toner delivery port 656 by the toner that toner conveyor screw 650 is carried.Conveyor screw 78 is sent the toner that falls into developing apparatus 54.Toner carrying roller 655 together rotates with the toner conveyor screw.When toner carrying roller 655 stopped, it closed toner delivery port 656, can prevent that like this toner in the toner Cartridge 642 from spilling.When toner carrying roller 655 rotated, the toner that is positioned at toner roller 655 tops was sent to the bottom, so that the toner in the toner Cartridge 642 can be sent from toner delivery port 656.Toner concentration sensor 658 detects the amount of the toner that is transferred.When the amount that detects predetermined toner when toner concentration sensor 658 is transferred, toner carry motor 647 be stopped, to stop the toner conveying operations.
It is fixed by moisture to prevent the toner in the toner Cartridge 642 that a stirrer is set.This stirrer is rotated through stirrer gear 645 by unshowned motor, with the toner in the agitation of toner box 642.A toner emptying sensor 646 is set in order to detect the amount of residue toner in the toner Cartridge 642.When toner was sent to developing apparatus 54, the amount of the residue toner in the toner Cartridge 642 reduced.Whether the amount that toner emptying sensor 646 detects the residue toner reaches predetermined value.When toner emptying sensor 646 detects the signal of just exporting an expression testing result when amount that remains toner in the toner Cartridge 642 has reached pre-determined bit.According to this signal, the conveying of toner stops, and the amount that the operator is apprised of in the toner Cartridge 642 the residue toner has reached predetermined value.
The amount of depositing in the toner in the toner Cartridge 642 is determined by this way, make the life-span of the amount of this toner, and also be enough big for the life-span that is sent to the developer the developing apparatus 54 from developer box 649 for the developer in the developing apparatus 54.When the amount of the toner in being stored in toner Cartridge 642 was definite in a manner described, this toner can be changed with developer.Therefore when changing developer, can save time and the labour.But when the amount of toner was too big, it was will be by moisture fixed or be subjected to high stress, and then reduces the charging performance of toner.
When toner is developed that roller 68 is delivered to photosensitive drums 48 and when printing, the amount of toner is reduced in the developing apparatus 54, like this, the concentration of toner is lowered in the developing apparatus 54.In this case, when toner when toner Cartridge 642 is delivered to developing apparatus 54, print operation and proceed.Because the developer in the All Time of printing in the developing apparatus 54 all is being stirred, so this developer quality degenerates, and becomes the developer that can not be recharged.
So the revolution of the life-span of developer by above-mentioned counting developer roll 68 detects.
When detection learns that the revolution of developer roll 68 has reached predetermined value (step 71), just carry out the discharging operation in order to the discharge developer that hereinafter will illustrate, developer in the developing apparatus 54 is discharged from, and with in the developer box 649 to developing apparatus 54 supplying developing agent.
Printing in the color electrostatic recording apparatus of operation (step 72), print operation and be stopped (step 72) according to a printing request.
Detect the amount (step 74) of developer in the developer box 649.
When the amount of developer in the developer box 649 during less than predetermined value, promptly when the amount of developer in the developer box 649 during less than the enough amount position of the developer that can flow to developing apparatus 54, then according to step 56 shown in Figure 5 to 58, the agent of request supplying developing.
When the amount of developer in the developer box 649 during, be discharged with the developer of crossing in the developing apparatus 54 greater than this predetermined value.Since the discharging with the mistake developer the time can not print operation, on display part 811, show (step 75) so inform the information that the operator stops to print.
When all developer has just racked up from developing apparatus 54, the lid motor 651 of developer box 649 is driven and opens conveying flap 652, make developer send into developing apparatus 54 from developer box 649, be simultaneously displayed on the conveying of the information notification operator developer on the display part 811, and stop to print operation (step 76).After developer was accelerated developing apparatus 54, it was transferred spiral 78 and is transported to developing apparatus 54.In this process, developer is delivered to developer roll 68 by defeated 9, and is stirred in developing apparatus 54, makes this developer charging.
For detection joins the toner concentration of developer in the developing apparatus 54, a toner concentration deboost is placed into (step 77).
After developer in developing apparatus 54 is changed, print operation and restart.
The discharge structure of developer
Fig. 9 to 11 shows from a plurality of developing apparatuss 54 and reclaims degree developer that is discharged and the structure that reclaims the waste developer that is discharged with clearer 60 from developer roll 48.
This structure comprises: a plurality of vertical tubes 91, a horizontal tube 92 that is connected with these a plurality of vertical tubes 91,93, one Vib. 97 and recycling cans 110 that the degree developer in the horizontal tube 92 is guided downwards of the developer conveyor screw of a supplying developing agent in horizontal tube 92.
The quantity of vertical tube 91 is six.Vertical tube 91-1 is connected with the floss hole of the developing apparatus 54 of electrostatic recording apparatus Y, and the waste developer that discharges from developing apparatus 54 is recovered.
Vertical tube 91-2 is connected to the floss hole of the developing apparatus 54 of electrostatic recording apparatus C, also is connected to the floss hole of electrostatic recording apparatus Y clearer 60.Like this, be recovered from the degree developer of developing apparatus 54 discharging of electrostatic recording apparatus C with from the degree toner of the clearer discharging of electrostatic recording apparatus Y.Vertical tube 91-3,91-4 are connected respectively to the floss hole of the developing apparatus 54 of electrostatic recording apparatus M, also are connected to the clearer 60 of electrostatic recording apparatus C.Like this, be recovered from the waste developer of developing apparatus 54 discharging of electrostatic recording apparatus M with from the used toner of clearer 60 dischargings of electrostatic recording apparatus C.Vertical tube 91-3,91-4 are connected to the floss hole of the developing apparatus 54 of electrostatic recording apparatus B, also are connected to the clearer 60 of electrostatic recording apparatus M.Like this, be recovered from the waste developer of developing apparatus 54 discharging of electrostatic recording apparatus B with from the degree toner of clearer 60 dischargings of electrostatic recording apparatus M.
Vertical tube 91-5 is connected to the floss hole of the clearer 60 of electrostatic recording apparatus B, and the degree toner that discharges from this clearer 60 is recovered.
A vertical tube 91-6 is set, for example strikes off the used toner of part from the endless belt 46a removing of endless belt conveying device 46 in order to reclaim by cleaning device.
Among vertical tube 91-2,92-3, the 91-4 each includes: a waste developer floss hole 94 that is connected with developing apparatus 54; With a degree toner floss hole 95 that is connected with clearer 60.Degree toner floss hole 95 meshes with the used toner floss hole 601 of clearer 60.A degree developer lid is installed in the top of used toner floss hole 95.By this degree developer lid, can not drop on and be accumulated in the top of the used toner floss hole 95 that meshes with vertical tube 91 from the developer of developing apparatus 46 dischargings.
Developer passes a plurality of vertical tubes 91 and falls into the horizontal tube 92 that links to each other with each vertical tube 91.A horizontal tube 91 only is set in this color electrostatic recording apparatus.When 93 rotations of waste developer conveyor screw, horizontal tube 91 reclaims developer through vibrating tube and falls into recycling can 110.Degree developer conveyor screw 93 is driven through gear 911 by unshowned motor.
The vertical tube 91 of recovery degree developer and horizontal tube 92 are installed in the behind of color electrostatic recording apparatus.In this state, the side door of this equipment can be opened, so that change photosensitive drums and remove the paper that is stuck in so-called front side.
Recycling can 110 also is installed in the behind of this equipment, so that the waste developer of carrying in horizontal tube 92 can fall into recycling can 110.Because said apparatus can reclaim waste developer under the situation of motor and gear at the conveying mechanism that the conveying waste developer is not set such as spiral.A recycling can only is set in this structure.Therefore, can use the space that this recycling can is installed effectively.In addition, a recycling can only is set, is easy to the replacing of recycling can.
Recycling can 110 can move between the removal position of the recovery position of waste developer and this recycling can, and promptly recycling can 110 can move between the front portion of this equipment and inside.When recycling can 110 was moved to waste developer recovery position, it was fixed, and it can not be moved.Figure 12 is the example of this set.A wheel 115 that is provided with rotationally and can moves along track 114 is arranged in the bottom of the retaining part 117 that recycling can 110 is set.For reclaiming location positioning recycling can 110, a locking spring 116 is set on track 114 at waste developer.The part of locking spring 116 is from stretching out with the surface of wheel 115 tracks that contact 114.When recycling can 110 enters into waste developer recovery position, the extension locking wheel 115 of locking spring 116, thus wheel can not be moved along track 114.Because above-mentioned setting can be positioned at recycling can 110 this recovery position with a simple structure.Track 114 tilts to this equipment front side.Therefore, even when recycling can 110 is full of waste developer, draw it with low intensive power, it also shifts to this equipment front side easily.
When recycling can 110 degree of filling developers and need replacing, the operator unclamps the locking of recycling can 110, holds handle 113 it is pulled out along this track.After with slack tank this recycling can 110 being changed, operator grasps handle 113 pushes it along this track and reclaims the position.Then, recycling can 110 is fixed on and reclaims the position.A lid 111 is set to be used for when recycling can 110 is closed vibrating tube 97 from reclaiming when the recovery position is pulled out or pushed in the position.Lid 111 is pushed along the direction of pulling out recycling can by spring 112 all the time, and vibrating tube 97 can be closed when being drawn out with convenient recycling can 110.Because along with recycling can 110 is drawn out, lid 111 is closed vibrating tube 97, so even in the process of replacing recycling can 110 conveying degree developer, do not have waste developer to overflow into this equipment from vibrating tube 97 yet.When empty recycling can 110 was installed to the recovery position, vibrating tube 97 was opened, and degree of making developer can be recovered in the recycling can 110.
The discharging campaign of developer
When need discharged developer from developing apparatus 54, lid motor 542 was driven, to move discharging flap 541 and to open floss hole 540.When the conveyor screw 78a in the developing apparatus 54 was driven, the developer in the developing apparatus 54 was moved toward discharging oral-lateral 540.Then, the developer that is moved falls into horizontal tube 92 through vertical tube 91.When 93 rotations of used toner conveyor screw, the developer in the horizontal tube 92 is sent to vibrating tube 97.After waste developer was taken in the vibrating tube 97, it was recycled to recycling can 110.
When whole developers were learnt in detection from developing apparatus 54 dischargings, lid motor 542 was driven and moves discharging flap 541, then floss hole 540 is closed.
Then, the lid motor 651 of Delevoping cartridge 649 is driven, and moves input flap 653.Like this, open developer input port 654, is input to developing apparatus 54 with the developer of the essentially identical capacity of capacity of developing apparatus 54.When lid motor 651 was driven, floss hole 540 was discharged flap 541 and closes.Send into the conveyor screw 78a that the developer of developing apparatus 54 is arranged on this developing apparatus from developer box 649 and send into developing apparatus 54.
The structure of developer carrying device
The formation of developer carrying device 64 is shown in Figure 13,14 (a), 14 (b).
The thin portion structure of the dividing plate 120 shown in Figure 14 (b), this dividing plate 120 have one be used for the gel silicone be pressed into toner Cartridge 642 and developer box 649 the coupling part be pressed into groove P.When the gel silicone is pressed into this when being pressed into groove, toner Cartridge 642 and developer box 649 can remain on airtight conditions.
Because this structure, the cycle of changing developer can prolong.
When the developer storing capacity (its access times are more than the access times of other developing apparatus) of certain developer carrying device in a plurality of developing apparatuss of color electrostatic recording apparatus during greater than the developer storing capacity of the developer carrying device of other developing apparatus, the developer in these a plurality of developing apparatuss can be changed together.So just can save the time and labor when changing developer.
Owing to can be recycled to the recycling can from the developer of developing apparatus discharging, so can automatically change developer.
Even when developer when a plurality of developing apparatuss and a plurality of clearer are recovered, the number that is used to reclaim the required vertical tube of developer also can be that the number with developing apparatus adds 1 and the numerical value that obtains.In addition, the horizontal tube that is connected with vertical tube also can have only one.Therefore, the structure of recovery developer is simple.
