Definitions
- the invention relates to a sleeve for transporting a toner mixture on its outer surface in a toner developing device, the wall of the sleeve consisting essentially of an electrically conductive material.
- the invention further relates to a method for producing such a sleeve.
- image development processes are used which develop electrostatic charge images on surfaces, preferably on photo conductor surfaces, via an air gap or in direct contact with triboelectrically charged toner.
- the toner is often designed as a two-component mixture of toner particles and ferromagnetic carrier particles. This two-component mixture is transported on its surface with the aid of a sleeve, this sleeve containing magnets on the inside, the magnetic field of which forms a magnetic brush on the surface of the sleeve with the aid of the ferromagnetic carrier particles and which also transports the toner particles.
- DE-A-2846430 describes a sleeve for a toner developing device, on the surface of which a two-component mixture is transported.
- conventional sleeves use aluminum as the material in which eddy currents are generated due to the varying magnetic field, which cause the toner material to heat up and soften. It is therefore proposed to use a material with a high electrical resistance in order to reduce the eddy current effect.
- the sleeve is made of a copper-nickel alloy and the outer surface of the sleeve is provided with grooves parallel to the axis.
- sleeves for transporting a toner mixture are also used in cleaning devices within a developing device.
- DE-A-10152892 gives an example of this.
- aluminum is usually used as the sleeve material.
- aluminum has the disadvantage that it is a relatively soft active substance, the surface of which wears off over time in the printing operation. This can lead to a loss of quality in the printed image.
- it has been proposed to provide the aluminum sleeve with a nickel layer on its surface. Although this has the desired effect with regard to hardness, this alters the electrical resistance of the entire sleeve, which leads to a negative influence on the electromagnetic properties on the surface of the sleeve.
- Another problem with transport sleeves for toner is oxidation on the transport surface.
- aluminum sleeves aluminum oxide can form on the surface.
- the oxide layer also changes the properties of the sleeve material, for example the electrical resistance, and thus the electromagnetic parameters at the junction of the sleeve and the photoconductor drum.
- This object is achieved for a sleeve of the type mentioned above in that the outer surface of the sleeve receives a layer of nickel-copper.
- this alloy layer has the required hardness and thus low abrasion, which results in a long service life.
- such a layer has a high electrical conductivity, which results in favorable electromagnetic properties.
- the electrical resistance of this layer can be optimized by adjusting the alloy ratio.
- Such an alloy layer can be magnetized only slightly or not at all, so that disadvantageous residual magnetism is avoided.
- the combination of high electrical conductivity and high hardness means that previous aluminum sleeves can be exchanged for the sleeve according to the invention without having to change electromagnetic or mechanical parameters to a large extent. Oxidation of the surface is avoided by the alloy layer.
- FIG. 1 shows a hollow cylindrical sleeve for transporting toner, Figure 2 and Figure 3 process steps for producing the surface layer for the sleeve made of aluminum.
- FIG. 1 shows a cylindrical sleeve 10 with a surface cutout A.
- a sleeve 10 can, for example, have a length L of 500 mm, an outside diameter d of 60.5 mm and an inside diameter of 56 mm.
- the sleeve 10 is preferably made of aluminum and has on its outer surface a layer of nickel-copper with a thickness in the range from 15 to 25 ⁇ m.
- This layer is produced by chemical deposition, with chemical nickel-copper-phosphorus deposition taking place.
- the layer typically contains 1 to 2% copper and 8 to 10% phosphorus, the rest being nickel deposition.
- FIGS. 2 and 3 show, using a flow chart, the chemical surface treatment for producing the sleeve with the nickel-copper layer.
- First the aluminum sleeve is degreased in alkaline solution (step 20). This is followed by a rinsing step 22. In the subsequent step 24, pickling takes place in 30% NaOH. This is followed by a rinsing step (step 26).
- step 28 there is clarification in HN0 3 , ie pickling in nitric acid 1: 1 after the alkaline pickling. Because brown to black pickling sludge forms on the surface after the alkaline pickling, depending on the material composition, it is then clarified in nitric acid to prevent the formation of A10 3 .
- a rinsing step 30 then takes place again.
- step 32 an electrical conductive layer is applied in a zincate stain. With help This conductive layer also neutralizes the oxide layer on the aluminum material.
- a rinsing step 34 then takes place.
- Figure 3 shows the subsequent rinsing step 36 with demineralized water, i. H. demineralized water from which all minerals have been extracted in an ion exchanger.
- demineralized water i. H. demineralized water from which all minerals have been extracted in an ion exchanger.
- the surface is chemically pre-nickel-plated.
- there is an economy flush. Saving rinsing involves rinsing in a container without water supply, which increases the concentration in the sink. The contents of the sink can then be returned to the chemical nickel bath or processed otherwise. Carryover losses are thus reduced. This is followed by rinsing in demineralized water in step 42.
- the chemical deposition process takes place with the nickel-copper-phosphorus deposition, which comprises a deposition of 1 to 2% copper, 8 to 10% phosphorus and the rest essentially nickel deposition.
- rinsing takes place in demineralized water. This is followed in step 48 by washing in water at 60 ° C., the nickel-plated parts remaining in demineralized water for 2 to 3 minutes before drying.
- the sleeve produced in this way is dried in warm air.
- step 44 An example of a bath batch for nickel-copper-phosphorus deposition is given below in step 44, the composition being given in g / 1:
- the sleeve produced in this way can be used as a transport sleeve for transporting a two-component toner mixture in developing devices.
- Toner can be transported between rollers or in the form of an applicator element in the immediate vicinity of a photoconductor surface.
- Such a sleeve can also be used as a cleaning device.
