No. 4071361), but generally they utilize a photoconductive substance, An electrical latent image is formed on a photoreceptor by various means, and if necessary, the toner image is transferred to a transfer material such as paper, and then fixed by heat, pressure, etc. to obtain a copy.

The magnetic brush method described in specification No. 2874063,
The cascade development method described in Specification No. 2618552, the powder cloud method and fur brush development method described in Specification No. 2221776,
Many development methods are known, such as liquid development. Among these developing methods, a magnetic brush method, a cascade method, a liquid developing method, etc., which use a developer mainly consisting of toner and carrier, are in particular widely put into practical use. All of these methods are excellent methods in which good images can be obtained relatively stably, but on the other hand, they have common drawbacks associated with two-component developers, such as deterioration of the carrier and fluctuations in the mixing ratio of toner and carrier.

という欠点を有している。 US Pat. No. 3,909,258 proposes a developing method using an electrically conductive magnetic toner. In this method, conductive magnetic toner is supported on a cylindrical conductive sleeve having magnetism inside, and is brought into contact with an electrostatic image to be developed. At this time, in the developing section, a conductive path is formed by the toner particles between the surface of the recording medium and the surface of the sleeve, and charges are guided from the sleeve to the toner particles through this conductivity, thereby creating a connection between the electrostatic image and the image area. Toner particles adhere to the image area due to Coulomb force and are developed. This developing method using conductive magnetic toner is an excellent method that avoids the problems associated with the conventional two-component developing method. It has the disadvantage that it is difficult to electrostatically transfer it to a permanent support member.

ある。 As a developing method using high-resistance magnetic toner that can be electrostatically transferred, Japanese Patent Application Laid-Open No. 52-94140
The publication discloses a developing method that utilizes dielectric polarization of toner particles. However, such a method inherently has drawbacks such as slow development speed and insufficient density of the developed image, and is difficult in practice.

あつた。 Another developing method using high-resistance magnetic toner is a method in which the toner particles are triboelectrified by friction between the toner particles or friction between the toner particles and a sleeve, etc., and the toner particles are brought into contact with an electrostatic image holding member for development. It has been known. However, these methods have drawbacks such as the number of times the toner particles come into contact with the friction member is small and frictional charging tends to be insufficient, and the Coulomb force between the charged toner particles and the sleeve increases and they tend to aggregate on the sleeve. This made it difficult to implement in practice.

得られるものである。 However, in JP-A-55-18656, etc.
A new development method has been proposed which eliminates the above-mentioned drawbacks. This involves applying a very thin layer of magnetic toner onto the sleeve, triboelectrically charging it, and then developing it in close proximity to the electrostatic image. This method increases the chances of contact between the sleeve and toner by applying an extremely thin layer of magnetic toner onto the sleeve, which enables sufficient frictional electrification, supports the toner by magnetic force, and connects the magnet and toner. By moving the toner particles relative to each other, mutual agglomeration is eliminated and sufficient friction with the sleeve is achieved, and the toner is supported by magnetic force and developed by facing the electrostatic image without coming into contact with it. Excellent images can be obtained by preventing background fog.

点で、その特性の十分なる吟味が必要とされる。 Ferromagnetic elements and alloys and compounds containing these elements (for example, compounds containing iron, cobalt, nickel, manganese, zinc, etc., such as magnetite, maghemite, and ferrite) have been known as magnetic materials for magnetic toner. . The various properties required of such magnetic materials include, for example, (1)
Maximum magnetizing force σm of about 40emu/g or more, (2) 150 ~
Coercive force Hc of about 500 Oe, (3) specific electrical resistivity of 10 2 to 10 7 Ω-cm, (4) blackness sufficient for practical use, (5) good moisture resistance, (6) good bonding with resin. Mixability etc. are known. Usually, magnetite, which is called iron black and is commonly used as a pigment, is often used in magnetic toners, and there are many examples described in various patent documents. This magnetite generally satisfies the above requirements, but for use in insulating magnetic toner, its properties must be carefully examined in terms of miscibility with resin, toner cohesiveness, triboelectric charging properties, and durability. It is said that

安定に保持する特性を強く要求される。 When a one-component magnetic toner is supported by magnetic force, is faced to an electrostatic charge image without contacting it, and is developed by applying an alternating electric field and a bias electric field during development, individual developer particles are , Coulomb force with the electrostatic charge image, magnetic force with the magnetic brush forming magnet, force due to an alternating electric field, etc. act. Particles on which a large Coulomb force acts are attracted to the electrostatic charge image, while particles on which a large magnetic force acts are attracted toward the developing sleeve, and development according to the electrostatic charge image is achieved. Furthermore, when transferring the magnetic toner developed on the photoreceptor onto transfer paper, a corona discharge with the opposite polarity to the charge polarity of the magnetic toner, that is, the same polarity as the electrostatic latent image, is performed from the back of the transfer paper. Then, the toner image is attracted to the surface of the transfer paper. At this time, if the charge on the toner particles easily escapes and disappears, the transferred image will be blurred or the transfer efficiency will be reduced. That is,
Since magnetic toner contains a relatively large amount of magnetic powder as its constituent component, it is strongly required that the magnetic powder has the property of stably retaining an electric charge.
又、従来の1成分トナーには磁性体が20〜80重

があつた。 Further, since conventional one-component toners contain 20 to 80% by weight of magnetic material, they have the disadvantage that it is difficult to fix the toner on copy paper by heat fixing or pressure fixing.

た。 On the other hand, recently, the purposes of use have become more diverse, and there is a desire for a compact and inexpensive multi-color copying machine that can produce images in desired colors as needed. The color tone of the magnetic material cannot be hidden simply by adding a coloring agent to the binder resin. For example, in JP-A-51-42539, it is recorded that magnetic powder is coated with a white pigment by chemical treatment, but the amount of magnetic powder and dye/pigment must be within the range that does not adversely affect the development characteristics. However, simply applying a chemical treatment to cover the magnetic material was not effective enough to hide the color tone of the magnetic material. In order to obtain a toner with the desired color tone using the above method, it is possible to reduce the amount of magnetic material more than necessary or increase the amount of coloring pigment, but if the amount of magnetic material is reduced too much, the developability will deteriorate. When the amount of the color pigment decreased or increased too much, problems such as a decrease in developability and a decrease in fixability occurred. It has been difficult to produce magnetic toners that satisfy all characteristics such as developability, color tone, and fixability.

Sleeve transportability deteriorates and development characteristics deteriorate.
If the amount exceeds this range, the electrical properties and fixing properties will deteriorate, and when used as a color toner, the color will become cloudy and vivid colors will not be obtained.

ー製造法等、それぞれの方法が応用出来る。 When producing toner, the constituent materials are thoroughly kneaded using a thermal kneading machine such as a hot roll, kneader, or extruder, and then obtained by mechanical crushing and classification, or in a binder resin solution. Magnetic powder can be obtained by dispersing a material such as magnetic powder in a liquid and then spray-drying it, or by mixing a specified material with a monomer that should constitute a binder resin and then polymerizing this emulsified suspension. Each method can be applied, such as a polymerization method to obtain a toner and a toner manufacturing method.
