Definitions

  • the invention relates to a method and a device for developing an electrostatic latent image produced on a recording medium with an electrically charged one-component developer which is conveyed onto the surface of the recording medium by a developing roller.
  • Such a method and such a device are known from DE-OS 29 19 804, which describes a method in which a developer application device with a conductive, elastically flexible, endless surface is brought into contact with the recording medium with a certain pressure and a one-component -Developer developed the latent charge image on the record carrier.
  • the developer application device and the recording medium are moved in the same direction and the peripheral speed of the developer application device is somewhat greater than that of the recording medium.
  • the device used for the method has a cutting edge electrode, which rests with a certain pressure on the surface of the developer application device and charges the one-component developer by charge injection with a predetermined polarity.
  • the ratio of the peripheral speed of the developer is in the range from 1.1: 1 to 1.5: 1.
  • a disadvantage of the two-component developers is that there is always a large amount of developer in the development system, which, owing to the long dwell times of the toner in the developer, reduces the quality of the former by grinding processes and accelerates the aging process of the entire developer.
  • Magnetic one-component developers have it not mentioned disadvantages, however, magnetic components such as magnetic brushes are required for their transport, which are expensive to manufacture. A certain difficulty also arises in the case of magnetic one-component developers in that, owing to their magnetic constituents, they have greater electrical conductivity and the triboelectric charging of the magnetic toner is thereby made difficult.
  • a developing device for a one-component developer in which a thin uniform layer of insulating non-magnetic one-component developer is formed on a E ntwickleritati and a latent image carrier with respect to set to an on this to develop generated latent image.
  • an application device is provided which, for example, has a grid and a pressure element for pressing the grid onto the developer carrier.
  • a developing device for a two-component developer with a magnetic brush is known, on the circumference of which a roller brush rests.
  • the roller brush scatters the developer from the surface of the magnetic brush and wires are provided to remove the developer from the bristles of the roller brush.
  • the resulting developer wolke moves towards a photoconductor drum that carries the latent image to be developed.
  • a wire mesh is arranged at a short distance from the surface of the photoconductor drum, which is designed as a counter electrode to the photoconductor surface and is intended to prevent toner particles with insufficient charge from reaching the recording medium. Retained particles lead to the clogging of such networks.
  • the developer can build up and compress under pressure and thereby form a uniformly thick and evenly charged toner layer can be prevented.
  • the object of the invention is to provide a method and a device which, while avoiding the caking of the particles of a one-component developer, enable a uniform formation of the layer thickness of the one-component developer on the developing roller without layer-limiting devices such as a doctor blade, a grid or similar elements and charge the one-component developer evenly and sufficiently on its way to the developing roller.
  • the object is achieved according to the invention by a method According to the preamble of claim 1 solved in that the one-component developer is charged by rotating charging devices, transported in the direction of the developing roller and additionally charged when separated from the charging devices.
  • the one-component developer is preferably additionally charged by triboelectric charging when it is separated from the surfaces of the charging devices.
  • the rotating charging devices come into contact with fixed scraper devices, which quickly separate the one-component developer from the charging devices and fling it onto the peripheral surface of the developing roller.
  • the layer thickness on the developing roller can be regulated by varying the rotational speeds of the charging devices and the developing roller, the rotating speed of the charging devices rotating at the same speed preferably being greater than the rotating speed of the developing roller.
  • the device according to the invention for developing an electrostatic latent image generated on a record carrier with an electrically charged one-component developer, with a developer roller arranged at a short distance from the record carrier and a developer feed device for the one-component developer is characterized by this from the fact that one-component developer can be fed from the developer supply device to the surface of one of the charging devices, that the surfaces of the two charging devices are spaced apart from one another by less than each of the distances of the charging devices from the developing roller, and that each charging device is assigned a wiping device which is associated with the surface the charging device is in grazing contact.
  • the charging devices are designed as brushes made of electrically conductive material and the cylindrical core of each charging device is connected to the same pole of a voltage source, the other pole of which is connected to ground.
  • a design with electrically insulating, but electrostatically chargeable brushes is also possible. Electrically conductive brushes are preferred because of controllable charging, also to prevent the charge from exceeding a certain size, i.e. runs away or becomes too high. The charging is controlled in a controlled manner with variable potentials.
  • the advantages are achieved that the charging of the one-component developer with simply constructed charging devices in the form of brushes takes place, the potential and thus also the charging of the one-component developer can be easily controlled, that the developer layer on the developing roller can be regulated by the speed of rotation of the brushes and the developing roller without a layer-limiting doctor blade, and that to supplement the discharge from the developing device by each image development Only small amounts of developer need to be supplied to it, which can be triboelectrically quickly, well and uniformly charged to the desired voltage in order to keep the total charge of the developer in the developing device at a predetermined value.
  • the embodiment of the developing device according to the invention shown schematically in FIG. 1 comprises two charging devices 1 and 2, which are designed as brushes with a cylindrical core 22 and 23, respectively.
  • the material of the brushes is electrically conductive and steel wire brushes, for example made of abrasion-resistant materials such as CrNi steels, are preferably used.
  • the surfaces or the peripheral surfaces of the two charging devices 1 and 2 are at a distance from one another which is smaller than the respective distance of the individual charging device from a developing roller 3 which is arranged above and at approximately equal distances from the roller surface to the stripping devices.
  • the two charging devices 1 and 2 are enclosed by a trough 5, the shape of which is adapted to the cylindrical peripheral surfaces of the charging devices 1 and 2 and preferably consists of the same material as the charging devices.
  • the distance between the inside of the tub 5 and the peripheral surfaces of the charging devices 1 and 2 or, in the case of brushes as charging devices, the distance between the inside of the tub 5 and the tips of the bristles of these brushes is of the order of 0.2 to 1 mm .
  • the distance is chosen so that contact between the tub and brushes is avoided to prevent abrasion. Due to the volume of the tub 5, which limits the charging devices 1 and 2, small amounts of developer are sufficient to carry out a satisfactory charging of the toner.
  • the single component developer 13 is by a metering roller 21 near the outlet of a developer supply device 20, in which a supply of developer 13 is filled, is metered and reaches the surface of the first charging device 1, which rotates counterclockwise, for example, as well as the second charging device 2.
  • the metering amount of developer 13 the amount required to supplement the developer consumed by the image development is about 50 to 100 mg, with an average density of the copy, which is about a hundredth of the amount of developer in circulation.
  • This amount of developer is both potential and triboelectric, as will be described in more detail below, quickly and easily rechargeable, so that a decrease in the charge of the one-component developer 13 does not occur due to the newly supplied, uncharged one-component developer.
  • the total electrical charge of the one-component developer in the developing device is therefore kept largely constant during operation.
  • the cylindrical cores 22 and 23 of the two charging devices 1 and 2 are connected to the same pole of a voltage source 9, the other pole of which is grounded. If, for example, a positively charged one-component developer 13 is used, the voltage which is applied to the two charging devices 1 and 2 with the same polarity as that of the developer is approximately +500 to +800 volts, in particular +600 volts.
  • a grid 18 for further toner charging is arranged, which is connected to the tub 5.
  • a scraper 4 is integrally connected to the grid 18 and is in contact with the bristles of the charging device 1.
  • the material of the grid 18 is preferably metal, but it can also be made of plastic.
  • One-component developer 13 is conveyed through the grid 18 from the charging device 1 to the charging device 2. As it passes through the grid, the one-component developer 13 experiences a further triboelectric charge, the magnitude of which depends on the grid material used in each case. Those developer particles that are not conveyed through the grid 18 remain stored between the bristles of the steel wire brushes of the charging devices 1 and 2 and, in the case of the first charging device, reach the area of the scraper 4, which extends as far as into the circumferential path or movement path of the charging device 1 protrudes that the tips of the individual bristles are held back by him and are released when the charging device 1 is rotated by a snap movement over the scraper 4.
  • This charge is composed of the charge which the charging device 1 gives to the developer particles as a result of the voltage applied to it, for example +600 volts, and a triboelectric charge dung that occurs due to the rapid separation of the developer particles from the bristles during the stripping process by the stripper 4.
  • a scraper 7 also protrudes into the movement path or circumferential path of the second charging device 2, which holds back the individual bristles of the steel wire brush until the energy stored in them by the deformation is sufficient for the snap movement over the scraper 7.
  • the developer particles stored between the individual bristles are again thrown in the direction of the developer roller 3 and are both due to the voltage applied to the second charging device 2 of, for example, +600 volts as well as due to the triboelectric charging during the rapid separation of the developer particles from the individual bristles charged.
  • the two charging devices 1 and 2 are connected to the same voltage potential, but it goes without saying that the two charging devices can be set to different voltages if they are mounted in the device in an electrically insulated manner.
  • the tub 5 is preferably composed of two semi-cylindrical parts which are attached to a carrier 15.
  • the carrier 15 consists of electrically conductive or insulating material. In the former case, the carrier 15 has the same pole of voltage Source 9 connected like the cylindrical cores 22 and 23 of the two charging devices 1 and 2. If the carrier 15 is made of insulating material, the trough 5 is connected directly to the corresponding pole of the voltage source 9.
  • the wiper 7 is also connected to the pole of the voltage source 9, with which the cylindrical cores 22, 23 are also connected.
  • the two edges of the tub 5 are attached to side supports 16, 17, which are made of insulating material. On these side beams 16 and 17, an upper part 8 of the developing device is further fastened, which closes the top.
  • a further voltage source 10 is connected to the developing roller 3 and the applied voltage is, for example, in the range from -200 to -300 volts and thus has an opposite polarity to that of the charging devices 1 and 2.
  • a uniformly thick developer layer is formed on the peripheral surface of the developing roller 3 and can be selected in the range from 30 to 150 ⁇ m. Development takes place, for example, overhead and the recording medium 11, an endlessly revolving photoconductor belt with a latent charge image 14, is guided past the developing roller 3 at a distance which is slightly greater than the selected layer thickness.
  • the record carrier 11 is, for example, negatively charged to a voltage between -500 to -1000 volts, in particular to -600 volts.
  • the latent charge image 14 is shown schematically in FIG. 1 by small ones Circles that include a minus sign are indicated.
  • the positively charged developer 13 cannot be held back by the negatively charged developing roller with respect to the latent charge image 14 since the absolute amount of the negative voltage of the developing roller 3 is smaller than the absolute amount of the negatively charged photoconductor.
  • the latent charge image 14 is developed by the developer 13 into a powder image 12.
  • the speeds of the charging devices 1 and 2 are in the range of 100 to 200 revolutions per minute, while the speed of the developing roller is 50 to 80 revolutions per minute.
  • the ratio of the speeds of the charging devices and the developing roller is thus in the range from 1.2: 1 to 4: 1.
  • the voltage of the developing roller 3 Since the voltage of the developing roller 3 has the same polarity as the voltage of the recording medium 11, but its height is lower than the voltage of the charged image areas, ie the latent charge image 14 on the recording medium 11, and on the other hand it is higher than the voltage of the non-image areas, these are the unloaded locations of the record carrier 11, it is ensured that the background of the copies is largely free of developer.
  • the underground freedom the copies can be largely controlled by the size of the voltage applied to the developing roller 3.
  • the stripped developer trickles down onto the bristles of the first charging device 1 and is taken away by them again.
  • the amount of one-component developer in circulation is small, and accordingly the dwell time of the one-component developer in the developing device is very short.
  • the used one-component developer is metered in as a function of an optical measurement of the blackening on the developing roller 3, which optical measurement is not described in detail. Studies have shown that about three quarters of the total one-component developer amount is applied to the developing roller 3 by the first charging device 1, while the remaining amount of developer reaches the developing roller 3 through the second charging device 2.
  • the separation speed of the one-component developer 13 from the bristles By choosing the mechanical sizes, such as the diameter and length of the bristles of the charging devices 1 and 2, the material of the charging devices and the wipers 4 and 7, and the speeds of the charging devices and the developing roller 3, the separation speed of the one-component developer 13 from the bristles and thus determining the magnitude of the triboelectric charge.
  • FIG. 3 schematically shows an embodiment of the developing device which is suitable for a recording medium which is stretched over the peripheral surface of a drum 24, a so-called photoconductor drum.
  • the developing roller 3 is in the D reiuhr-position of the drum 24 opposite, as is a Neunuhr position possible, while the two charging devices 1 and 2, which are formed by brushes obliquely, are arranged below the developing roller.
  • the same parts are given the same reference numerals in the embodiments according to FIGS. 1 and 3. 1 to 3, the developer is sprayed onto the surface of the developing roller 3 essentially in the radial direction.
  • FIG. 4 shows an embodiment of the developing device which works with a single charging device 26 in the form of a brush and in which the developer requests the developing roller 3 tangentially.
  • the metal core of this charging device 26 is connected to the one pole of the voltage source 9, as is a stripper 27 which cooperates with the bristles of the charging device 26.
  • the mode of operation is analogous to that which was described with reference to FIG. 1.
  • the developer particles stored on the bristles and between the bristles are thrown upon contact with the stripper 27 onto the peripheral surface of the developing roller 3, which is connected to the one pole of a further voltage source 10 and has a voltage opposite the voltage of the charging device 26 .
  • a uniformly thick developer layer is formed on the peripheral surface of the developing roller 3, from which the developer onto the recording medium on the drum 24 corresponds accordingly latent charge image located on the recording medium.
  • the remaining developer on the E ntwickelwalze 3 is brushed off by the scraper 19 is removed and reaches a collecting roller 25 from the peripheral surface of the developer through the bristles of the charging means and the developing is supplied again, the toner charge in turn previous to by the applied voltage Is brought up.
