Below, the toner replenishing for the developing device 23 to the features as this printer is described.
First, as illustrated in fig. 2, in developing device 23K, be provided with the allowance detector 302K that the Toner allowance in developing device is detected.Specifically, after in developing device, piezoelectric sensor is set, the surplus in developing device is detected by the output of piezoelectric sensor, or detection window is set in developing device, by infiltration type optical sensor to after whether having toner to detect in detection window, toner volume height in developing device is detected, and detects surplus from this volume height.
By allowance detector 302, when control part 300 detects that toner amount in developing device is lower than certain threshold value, control part 300 is just judged as that toner is finished, and will the content report of toner replenishing be needed to user by the annunciators such as display panel 303, and user be urged to carry out toner replenishing.User according to the instruction of annunciator 303, by the toner replenishing of new product to developing device 23 li.
New product toner T1 is because be added on not departing from for the adjuvant adjusting mobility and charging property or being embedded in particle in surfaces of toner particles, so have good charged characteristic.But along with the increase of lettering number of pages waits because stirring and is subject to stress, and adjuvant departs from or charged characteristic will decline after being embedded in particle, and become be difficult to charged.The toner of this charged deficiency is difficult to the impact of the potential difference (PD) be subject between developer roll and photoreceptor, thus can be attached to after in non-sub-image field and cause bottom surface to be made dirty.
Therefore, the developing bias as development conditions is applied to developer roll 81 li after controlling development power supply 301 according to the rotation number etc. of lettering number of pages or photoreceptor 24 by control part 300, and controls the developing bias of the deterioration state corresponding to toner.Then, after new product toner replenishing comes, the rotation number etc. of control part 300 pairs of lettering numbers of pages or photoreceptor resets, and is switched in the developing bias corresponding to new product toner T1.That is, control part 300 and development power supply 301 constitute development conditions change device.
Here, employing Fig. 3, Fig. 4 illustrates toner replenishing in the past.
It is the key diagram of toner replenishing in the past shown in Fig. 3.Here, because the formation of developing device 23K, C, M, Y of colors is all identical, so in the following description, omission color symbol is illustrated.
Developing device 230 be in the past on hopper portion 86 be provided with toner replenishing mouth 89, and be connected in this toner replenishing mouth 89 toner conveyance flexible pipe 111 one end.The other end of toner conveyance flexible pipe 111 is connected in the toner supply port 112a above the body housing 112 being arranged on printer.
When user is using when being placed in the toner supply port 112a of body housing 112 as the toner cartridge 110 in the developer receptacle portion being accommodated with new product toner T1, the new product toner T1 in toner cartridge 110 is just fallen to hopper portion 86 from toner replenishing mouth 89 by toner conveyance flexible pipe 111.Thus, toner just by supply to developing device 23 li.
It is the summary pie graph of the developing device 230 in the past after toner replenishing shown in Fig. 4.
As illustrated in fig. 4, new product toner T1 from toner cartridge 110 by unified supply to hopper portion 86 time, new product toner T1 can be stacked into above the old toner T2 that deteriorates, and on old toner T2 layer formation new product toner T1 layer.Even if stirred the toner in developing device by stirrer 88, be also difficult to the old toner T2 fully mixing new product toner T1 He deteriorate, therefore just in the bottom in toner hopper portion, form toner T2 layer of haveing been friends in the past.Consequently, toner unify supply just terminate after image to be formed be use old toner to develop substantially, with correspond to the developing bias of new product toner T1 carry out time, bottom surface will be there is and make dirty.So, also consider that unifying supply from toner terminates, to regulation lettering number of pages prints, to carry out with the developing bias corresponding to old toner T2.But, the amount of the old toner T2 remained in developing device is difficult to correctly hold by surplus testing agency 302.Specifically, when adopting piezoelectric sensor to be used as surplus testing agency 302, when being configured with the position of piezoelectric sensor and not having the position configured that toner amount biased occurs, will detect that at the stage place more than ormal weight surplus is the situation of ormal weight, or detect as ormal weight at the stage place fewer than ormal weight.Further, when adopting infiltration type optical sensor to be used as surplus testing agency 302, during the position generation toner amount configured when the position and being not have configured with detection window biased, just correct surplus can not be detected.Consequently, new product toner T1 can be used to development in the stage early than regulation lettering number of pages, or is used to development in the stage being later than regulation lettering number of pages.Its result can cause being difficult to carrying out best bias voltage control, and image quality such as sharply to change at the problem.
So in the present embodiment, developing device 23, relative to posture when being positioned in printer, is to be formed developing device 23 with carrying out toner replenishing with the posture in the vertical direction up and down after reversion.Be described as follows.
The key diagram of toner replenishing when being the developing device 23 to employing present embodiment shown in Fig. 5.
That surplus testing agency 302 detects the schematic diagram of the Toner allowance in developing device lower than appearance during ormal weight shown in Fig. 5 (a), shown in Fig. 5 (b) be by new product toner T1 supply to developing device time the schematic diagram of appearance, the schematic diagram of the appearance after new product toner replenishing shown in Fig. 5 (c), shown in Fig. 5 (d) be by new product toner replenishing after the posture schematic diagram of developing device 23 when being arranged in printer.
As shown in Fig. 5 (c), the developing device 23 of present embodiment is unified supply under the state in developing device 23 at new product toner T1, when posture when settling relative to printer becomes posture (hereinafter referred to as " reversion posture ") after reversing up and down in the vertical direction, at the water plane than the toner in hopper portion 86 more by arranging toner replenishing mouth 89 in the position of vertical direction.Specifically, as Suo Shi Fig. 5 (a), be make the photosensitive side in hopper portion 86 (in figure left side) more outstanding to photoreceptor side from developer roll 81, and in opposite directions in the right face 90a position more outstanding in left side in figure than developer roll 81, toner replenishing mouth 89 be set at hopper portion 86 and developer roll 81.In beyond toner replenishing, cover 90 is installed in toner replenishing mouth 89 to block toner replenishing mouth 89.
As Suo Shi Fig. 5 (a), when the toner amount in developing device is lower than ormal weight, surplus testing agency 302 is detected this and is reported to by the annunciator 303 of display panel etc. after user takes off developing device 23 with urgency and carries out toner replenishing.
Developing device 23, according to the instruction of above-mentioned annunciator 303, after rotating upper cover 56 and light write assembly 27 (with reference to Fig. 1), goes out to direction lira vertically upward and takes out from body by user.Then, as Suo Shi Fig. 5 (b), relative to the posture (hereinafter referred to as " normal position ") when being positioned in printer, be developing device 23 is become 120 li, the platform that the posture (reversion posture) after reversing up and down was in the vertical direction placed into desk etc. afterwards.The 86a above (becoming below after the posture after reversing up and down in the vertical direction) in the hopper portion 86 of developing device 23 is the faces being parallel to surface level.Therefore, even if discharged-area development assembly, also can stably be placed on the surface level of platform 120 grade.
In addition, when being placed on platform 120 by developing device 23 with posture of reversing, the 86a above (below during reversion posture) that the old toner T2 remained in the below in hopper portion 86 just drops to hopper portion 86 is inner.
So, to reverse, developing device 23 is placed on after on platform 120 by posture, takes off cover 90 from toner replenishing mouth 89.Then, toner cartridge 110 is arranged to 89 li, the toner replenishing mouth of opening.Toner replenishing mouth 89 is because be arranged on more outstanding to photoreceptor side than developer roll 81 and in right position, so toner cartridge 110 would not interfere with developer roll 81 li, and can not be arranged to 89 li, toner replenishing mouth in opposite directions with developer roll.After toner cartridge 110 being arranged to 89 li, toner replenishing mouth, pull off the sticky not shown seal member be posted in the toner supply port 110a of toner cartridge 110, and from toner replenishing mouth 89 by the whole unified supply of new product toner T1 that is accommodated in toner cartridge 110 to hopper portion 86 li.
