Abstract

To accurately control the image density with limited numbers of sensors. A long tape-shaped patch is formed in the axial direction of the photo-sensor based on the difference (contrast potential) of the charged potential from BCR3 and development bias without ROS4. The toner correction value computing portion 22 computes the correction value of toner supply based on the density of the tape patch detected by the density sensor 6. With this correction value, it corrects the indicating amount of toner supply according to the image amount. The toner detecting portion 23 detects the condition that the toner supply device 51 becomes empty due to the density change of tape patch. The impressed voltage of BCR3 and the development bias are corrected in accordance with the consumption quantity of photo-sensor 1, charged power and environment conditions, etc.

Description of the invention (ί) [Technical Fields of Invention] < " Read the notes on the back before filling in this page) The invention is suitable for circular image forming devices, especially for copying machines and flutes "Printing and printing equipment using a two-component reversal development method for the gardener's garden photography forming device" [Knowledgeable technology] Photographing for gardener's gardening equipment such as post printers and laser printers In the formation device, the characteristics of the "light-emitting body and the display" are changed, and the thickness and grade are changed. The characteristics of the light-emitting body and the display strip are subject to change, so it is not easy to maintain a certain constant. _Image density β In a full-color image formed by the superposition of two color tones, the toner density of each color will swell the image density, so the stability of the image is stable. There will be difficulties. For example, since the alumina and photosensitivity deteriorate with the passage of time, the density of the two-component imaging application is appropriate, but due to the long-term use, there is a tendency to reduce the concentration. When the amount of toning is increased to make the image look like a degree a, the other aspect is that the concentration of the toning is different from the value of the toning, and it will cause poor quality such as mottled and broken text. Two Questions · In the Ministry of Economic Affairs, the standard of -1-Beibei Consumers Cooperatives Co., Ltd. ^ In view of the characteristics of the filming methods of Xunzi and other crickets, there are various technical proposals to improve the _image density lattice. β For example, in the garden image forming apparatus described in Japanese National Patent Case No. 61-254961 and Japanese Unexamined Patent Application No. 3-980β 4K, a position holder is used (KSV) to detect the formation of the light on the blue part. The surface potential can be controlled at the target value by controlling the conditions of the band m and chirped light. In this way, you can use the density detection Lan Weilan device to detect the concentration of the surface nuclei formed in a certain way -3-This paper size applies the Chinese standard (CNS) Λ4 specification (21〇 × 297 mm) 412666 A7 B7 V. Description of the invention (concentration of the pattern (toner repairing surrounding image) used for checking the printing system of the printing system of the Central Government Bureau of Standards and Consumers' Work Cooperatives, according to the result of the density inspection, 1 is used to control the supply of The toner amount of the imager. After the surface potential of the opaque body is matched with the target value in this way, when a toner repairing crocodiles image is formed, the degree information of the toner repairing circle image is not detected. It is affected by the change in the photosensitivity of the photoreceptor. Also, the concentration of the toner patched image obtained from the density information can accurately reflect the amount of toner (colorant concentration) in the developer, so The control of the toner supply amount becomes easy, and as a result, a desired image density can be surely obtained in accordance with the charging and exposure conditions. The other quotient is, for example, Japanese Patent Application Laid-Open No. 4-152371 Documented A device for controlling the toner concentration in a developer to a certain degree of stability without causing the above-mentioned poor image quality. In this device, in order to maintain a certain toner concentration, the A toner concentration sensor is provided in the developer. In this way, according to the detection result of the toner concentration sensor, the amount of toner supplied to the developer is controlled so that the toner concentration becomes constant. This is a method for stabilizing toner concentration in general. In addition, in order to manage the toner amount in the toner supply device, in the conventional technology, an emptying detector provided in the toner supply device is used. The detector is used to detect toner emptying ^ However, in recent years, when the above toner concentration majestic tide device is used to roll out a multiple that indicates that the toner concentration has decreased several times in a row, it is recognized as a color tone. When the agent becomes empty, the number of sensors tends to be reduced. In Japanese Patent Application Laid-Open No. Hei 2-39178, a detection device is proposed to reduce the number of sensors, of which the counting figure is -4-nn- -ml ^ ^ 1 ^^^ 1 ^^^ 1 a ^ —Ί ^^ — ^ 1 --- (Please read first Read the precautions on the back and fill in this page) Order%, this paper size applies the Chinese National Standard (CNS) A4 specifications (210X297 Gong > A7 412666 B7 V. Description of the invention 0) {Please read the precautions on the back before filling (This page) The number of images, the number of images provided on the face, "When a certain value, it is considered that the toner that has formed a predetermined amount of image has been consumed (becomes a toner empty ^ Shape plug). [Problems to be Solved by the Invention] However, the above-mentioned conventional technology device has the following problems. First of all, according to the toner concentration, the toner concentration detected by the Qi Lan instrument is used to control the supply of toner. In the method, when the amount of toner box changes due to changes in thickness and humidity and the deterioration over a long period of time, the problem cannot be properly controlled. For example, due to color adjustment The degree of thin waterfall is suitable. In the situation where the amount of the two toning belts changes due to the deterioration of the loading, the combining force of the toning and the loading changes to make the amount of toning M on the velvet cross. "Changes" Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, In addition, in the method of recognizing that the toner becomes empty when the toner concentration performance has been lowered several times, one of the large amount of images occurs In the case of processing, the density will be temporarily reduced, but the actual situation is that the toner still has a sufficient residual amount. "· Therefore, the emptying judgment criterion of the color tone _ the number of times the density is reduced and the reduction is reduced. Levels need to be corrected, with the result that the control becomes Qi is mixed for the title between them. In addition, in the method of counting the sticky number of the image to push the toner consumption, because the relationship between the sticky number and the toner consumption varies with the type of image, there are many uncertain factors. There are still problems. From the results of the above review, it is best to have a device that can maintain the surface potential of the Weiguang plaque constant and detect the density of the brewing image. The device preferably contains a toner concentration device for coloration and emptying. Inspection _ This paper size is applicable to China National Standard Chinese Standard (CNS) A4 specification (2) 0 × 297 mm. The Central Consumers Bureau of the Ministry of Economic Affairs, the Consumer Cooperatives Co-print A7 412m% --- 5. Description of the invention u). However, because of the high price of potentiometers and color mixing devices, it is not possible to use the many low-speed machines that are used to adjust the high-speed machines, and it is another problem to improve the performance of low-speed machines. The purpose of the present invention is to provide an image forming device for eliminating the above-mentioned problems. When the number of Weilan devices is reduced, a certain plaque concentration can be maintained without generating poor image quality. The image forming device can control the B image density without using a very high position holder and a carburizer. The image forming device provided does not require the use of toner. It becomes a tester and can detect the color of the cocoon emptying. [Methods to solve the problem] The first state of the present invention for the purpose of solving the above problems is equipped with a charging device for making the above-mentioned garden image The surface carrying E is charged; the magnetron for temporal image is used to apply pressure to the toner and repair the formation device. The voltage application conditions of Juze's above-mentioned charging device and development magnetron are used to make the circle As described above For example, you can use the magnetron's pick-house voltage and the above-mentioned image carrier to carry a low-potential ion. You can use this method to make a reversal.

In step 6, set the desired repair image in step S1. ^ Concentration CIN. The awake degree CIN of this work is expressed by the sticky surface rate in the middle of the sticky repair circle. For example, it is set to 50% β. By transforming the paint concentration, CIS can be split into a multi-crane repair garden image. This embodiment is one of them. S2. According to the above-mentioned mapping concentration CIN driving ROS4 is used to form a sticky repaired round image PP on the BS photocell 1. For example, when the CIS concentration is 50X, the ratio between the 0S time of R0S4 and the OFF ratio is 1: 1. The repaired image at the point written by R0S4 is developed on the development device 5 β. At step S3, the image of the imaged gull is repaired. The degree of image PP is waiting. After waiting for a predetermined time, that is, At a predetermined time, when the patch is repaired to the position B, it will cause the concentration detector 6 to perform ONN β at step S4 to read the output of the concentration detector 6. The interval is performed a predetermined number of times. The basis of the predetermined time interval is the schedule from the point at which the point repairing image PP is turned ON to the time when R0S4 is turned on to the point where the K image is repaired to the position facing the concentration vial β. For a while. In the method of this embodiment, five extractions are performed at 20 millisecond intervals, and the detection value β of the gradation of 5 is read at step S5, so that the density detector 6 performs 0 F F.

The contrast angle used to form the patch repair image increases with the charging of the fans (the reduction of the ministry position increases.) In this way, the grid repair When the image density becomes higher, the toner concentration of the developer is controlled to be reduced, and finally the print image print density is reduced. Among them, as the consumption increases, the applied voltage of BCR3 increases. The 15th circle is the process circle of the control that increases the BCR3 journey plus voltage with the increase of the friction of Weiguang 酦 1. At step SiOd, 黩 replaces the friction of weiguang 钃 1 as the number. The cumulative number of revolutions (drum loops) η of Zhiwei 醑 1 is determined in step S101 whether the drum sugar number η is "Oj" because the initial value of the drum cycle number η is "0 Therefore, first proceed to step S102, and set the correction value AVab of the applied voltage for the repaired circle image of BCR3 to "0 j." When the drum cycle number η is not "0", proceed to step S103 and A * η is set as the correction value AVah constant A is the value of the correction value AVab for each drum cycle number η determined by the previous experimental value. In step S104, it is determined whether the correction value AVab has reached the upper limit value. AVabu (for example, 10 volts) If the result of this judgment is negative, proceed to step S105, and update the correction value AVab to the value β set in the above step S102 or S103. On the other hand, if the result of the determination in step S104 is When it is affirmative, proceed to step Ksioe, and set the correction value △ Vab to the upper limit value △ Vab ·, which is also 01.

Applied voltage VBPe of BCR3 used in the description of the invention (M) In the correction control of Fig. 15, the applied voltage of BCR is corrected, but it is not limited to this method. The target density with the repaired image "Figure 1G is a flowchart of the control to increase the target value of the concentration of BCR3 with the increase in the amount of friction of the Weiwei light body 1. In step S110, the number of drum cycles η of the photoreceptor 1 is read. In step SU1, it is judged whether the number of drum loops η is "0". First, the process proceeds to step S112, and the calibration target value ΔVab of the concentration target value of BCR3 is set to "0". When the number of drum loops η is not "0", the process proceeds to step S113, and β · η is set to the correction value ADab. The constant B is the value β of the correction value ADab for each drum cycle number η determined according to the experimental value in advance. In step S114, it is judged whether the correction value ADab has reached the upper limit value ADaba ^ If the result of the judgment is negative, Proceed to step S115, update the correction value △ Dab to the value β set in step S 11 3 above. On the other hand, if the judgment result in step S11 4 is affirmative, proceed to step S11G and update the correction value A Dab Set to the upper limit ZiDabB. That is, the correction value Δ Bab is positioned at the upper limit value in step S 117, and a value obtained by subtracting the correction value ADab from the initial value DBPI of the repaired image is set as the concentration target value DBP for the repaired image.
