Definitions
- the present invention relates to an image carrier having at least one Contains elastomer with cavities.
- the image carrier can, among other things They are used in electrography, electrophotography or magnetography.
- the central component in electrophotographic printing processes is the Photoconductor. With practically all today's electrophotographic color printers organic photoconductors are used. The thickness of the photoconductor is typically around 20 ⁇ m on an aluminum drum. Usually the photoconductor is neither elastic nor compressible. A detailed Description of the electrophotographic process can be found e.g. B. in "Electrophotography and Development Physics" by L. B. Schein, Springer Verlag, 1992, ISBN 0-387-55858-6.
- color printers typically use the four process colors Black, cyan, magenta and yellow worked in sequence on paper (or the intermediate carrier) are applied.
- a high quality Image requires a register accuracy of 100 ⁇ m or better between the Color separations.
- An intermediate carrier is used to achieve this accuracy difficult.
- roller 1 has an elastomeric cover 3 (for example rubber) and is employed on roller 2.
- Roller 2 and the core of roller 1 are made of non-elastic material compared to reference 3 (for example steel).
- the employment creates a contact zone 4, too Nip called, in which the elastomeric cover is deformed.
- roller 1 driven so that roller 2 is moved by friction of roller 1 the hard roller 2 has a higher surface speed than that of Roller 1 with an elastomeric cover firmly. This effect is considered more positive Designated slip.
- rollers 5a and 5b are photoconductors to US No. 5,828,931.
- Known facilities are shown here, but not known Photoconductor 5a generates a toner image of the first color and onto photoconductor 5b Image of the second color.
- Paper 7 runs in the direction of arrow 8 and is through Back pressure roller 6a first pressed against photoconductor 5a, so that the image of the first color is transferred to the paper. Then the paper pressed against counter-pressure roller 6b against photoconductor 5b and the second color will be transferred to the paper.
- the exact positioning of the two color images is problematic here to each other, in particular due to the deformation slip and manufacturing tolerances in the production of photoconductors 5a and 5b.
- For a good Image quality must have register accuracy at 100 ⁇ m or better (i.e. more precisely). This must also cover the entire paper surface can be achieved.
- the deformation slip lies in typical circumstances at about 1%. For a sheet of length A4 (29.7 cm), this corresponds to one Length difference of 2970 ⁇ m, which is considerably more than the desired 100 microns.
- three techniques are used to achieve the To keep deformation slip low: With known contact pressure, the Deformation slip can be measured.
- the second technique for reducing register errors is the same Employment for counter pressure rollers 6a and 6b, d. H. Back pressure roller 6a placed against the photoconductor 5a with the same force as the counter-pressure roller 6b against photoconductor 5b.
- the third possibility of correction is to make the reference as possible to be thick because the positive deformation slip is relatively small is held.
- the invention is based on the problem of providing an image carrier which has no or very little deformation slip, so that Problem of registration accuracy with the associated disadvantages is solved.
- the image carrier according to the invention is also intended as a photoconductor be usable.
- an image carrier the contains at least one elastomer with cavities.
- the elastomer is preferably a foamed polymer, in particular a foamed polyurethane, silicone, EPDM rubber and / or NBR. Foamed here means, for example, that the polymer is produced in such a way that a gas, for example nitrogen or CO 2 , is released during the production process. Alternatively, the gas can also be introduced during the production of the polymer. In both cases, an elastomer is created that contains cavities and has a relatively low density.
- the cavities in the Elasomer created by expanding hollow spheres or not expanding Hollow spheres, which are then expanded are introduced.
- Elastomers are in particular those mentioned above materials polyurethane, silicone, EPDM rubber and / or NBR. Such Systems based on polyurethane are described in German patent application DE 10111618.7.
- the thermoplastic hollow spheres are made preferably from an acrylate-vinylidene fluoride copolymer and contain a gas, for example butane.
- the volume fraction of the cavities in the elastomer is preferably 5 to 95%, especially 20 to 80%.
- the ratio of the voids to the elastomer Material can be easily optimized so that the Deformation slip is minimized. If the elastomer with the cavities has other components, such as a photoconductive or magnetic material, then the volume fraction of the voids in the Material containing the elastomer and additives, preferably 5 to 95%, especially 20 to 80%.
- the image carrier is a photoconductor.
- the photoconductor according to the invention is preferably used in one of the two following Embodiments provided:
- it can have at least two layers, one of which has at least one layer of photoconductive properties and at least one layer contains an elastomer with cavities. On the other hand, he can Contain layer that contains an elastomer and cavities and at the same time has photoconductive properties.
- a photoconductive layer is applied to an elastomeric layer with a thickness of 1 mm and a relatively low resistivity (e.g. less than 10 9 ⁇ m), which consists of polyurethane, which contains expanded hollow spheres.
- a relatively low resistivity e.g. less than 10 9 ⁇ m
- the elastomeric layer with the cavities itself has photoconductive properties.
- the photoconductors according to the invention have compared to known photoconductors
- the elastomeric layer with the cavities has a thickness of 1 mm.
- the layer has a Shore A hardness of 20 and a specific resistance of 10 8 ⁇ m. This value applies to a speed range up to approx. 0.5 m / s. At higher speeds, a lower specific resistance, inversely proportional to the speed, is required in the first approximation.
- the structure of the photoconductor is, in a first approximation, similar to that of conventional photoconductor drums, i.e.
- a barrier layer less than 1 ⁇ m thick on the elastomeric layer, then a generation layer for charge carriers about 1 ⁇ m thick (here charge carriers are generated by the incidence of light) and finally as the top one is an approx. 20 ⁇ m thick transport layer for load carriers.
- a thin (e.g. approx. 3 ⁇ m thick) and hard wear protection layer can be applied to the top layer.
- the number of layers can be reduced if one of the layers mentioned performs several functions.
- the photoconductors according to the invention without deformation slip, it is of The advantage of optimizing the ratio of cavity to elastomeric material. If the proportion of cavity is too high, you get a negative deformation slip, while with a very small amount of void receives a positive deformation slip.
- the percentage of void that needed to avoid the deformation slip depends in particular depends on the type and hardness of the elastomer used. It varies in particular between 5 and 95%.
- a fixed drum e.g. Aluminum with a wall thickness of 1 mm
- a rigid sleeve e.g. Aluminum with a wall thickness of 1 mm
- a flexible sleeve e.g. stainless steel with a wall thickness of 50 ⁇ m
- a flexible tape e.g. PET with a Thickness of 100 ⁇ m
- adhesion promoters can be used.
- no substrate is used.
- the photoconductor is then manufactured as a sleeve in the form described above on, for example, a drum and then removed from it.
- This has the advantage of low cost, since a substrate can be saved.
- the photoconductor is a wear component that has to be replaced relatively frequently (e.g. after 50,000 A4 pages), so that costs play an important role here.
- two configurations are preferred: First, a comparatively low specific resistance of the elastomeric material (e.g. less than 10 7 ⁇ m ) or secondly, a "highly conductive" coating inside the sleeve (example: an approx. 1 ⁇ m thick layer of graphite).
- the radius of curvature kept as large as possible for the photoconductor. This will reduce the burden of photoconductive materials kept as low as possible.
- a drum can be achieved by a large outer diameter (Example: 200 mm).
- this can be done by a sufficient length and a suitable tape guide can be achieved.
- the Invention in the layer containing the elastomer and the cavities, too the photoconductor included.
- the elastomeric layer is then the transport layer for the load carriers.
- the structure is as follows possible: a barrier layer less than 1 ⁇ m thick is applied to the substrate applied. Then there is the approx. 1 mm thick elastomer layer, the also serves as a transport layer for load carriers.
- the follows Generation layer (approx. 1 ⁇ m thick). Because such layers are typically can only be mechanically loaded (heavy wear in contact with Paper), here is a wear protection layer as already described above used.
- the advantages of the image carrier according to the invention are described above, also achieved in embodiments in which the Image carrier is not a photoconductor.
- the image carrier according to the invention is preferred also used for electrography and magnetography.
- Electrography or also ionography, as described in "Electrophotography and Development Physics” by L. B. Schein, Springer Verlag, 1992, ISBN 0-387-55858-6) is used instead of a photoconductor an electrically insulating layer.
- the present invention can here with the same advantages as with a photoconductor.
- you can an insulating coating can also be dispensed with by using the elastomeric material uses a highly insulating material.
- magnetography As described in "Electrophotography and Development Physics” by L. B. Schein, Springer Verlag, 1992, ISBN 0-387-55858-6.
- a photoconductive layer instead of a photoconductive layer used a magnetic layer here.
- One or more magnetic substances e.g. Magnetite.
- the image carrier according to the invention also for any other printing method applicable in which a toner image on a Image carrier created and from there without intermediate carrier on the substrate is transmitted, especially in color printing.
- the transfer takes place thermally, i.e. the toner will heated so that it melts and sticks there when it comes into contact with the paper.
- the elastomeric and photoconductive Layer be sufficiently temperature stable. Also, for the top one Layer used a material with low surface energy, so that the melted toner detaches well from the photoconductor for transfer to paper.
