The present invention relates to a developing powder for electrophotography. Electrophotography generally involves forming an electrostatic latent image on a photoconductor made of a photoconductive substance, developing this image with a powder developer to make it visible, and then fixing it with heat or a solvent. be. As a developer for such electrophotography, a mixture of a fine particle powder called a toner, which is made of a resin and a colorant, and microscopic glass beads or iron powder, called a carrier, is used. The present invention relates to this developing powder called toner. The photoconductor layer can be positively or negatively charged so that exposure under the original produces a positive or negative electrostatic latent image. Therefore, if the negative electrostatic latent image is developed with positively charged developer powder, a positive image matching the original is generated. However, when a positively electrostatic latent image is developed with negatively charged developer powder, the black and white tones are reversed and a negative image of the original, that is, a positive negative image is obtained. As described above, there are two types of developer powder for electrophotography: positively charged developer powder and negatively charged developer powder. Among these, the present invention relates to positively charged developer powder. Generally, developer powder is a fine powder made by mixing synthetic resin with coloring agents such as dyes and pigments. In order to positively charge the developer powder, the dye mixed therein plays an important role not only in coloring but also in its electrostatic properties as a charge control agent. Basic dyes such as nigrosine have been used as positive charge control agents, but the conventionally used dyes such as nigrosine have large variations in charging characteristics between production lots, and when made into toner, It has drawbacks such as poor durability against repeated continuous copying of toner. As a result of repeated research to solve the above problems, the present inventors have discovered a charge control agent that has positive charge control properties and good compatibility with resins, and have invented an excellent toner. It came to this. That is, the present invention is based on the following general formula (1) (In the formula, R 1 is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or 2 carbon atoms.

R 3 is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms,
Represents an optionally substituted phenyl group, R 4
represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a halogen atom, M represents a chromium atom or a cobalt atom, and X represents an anion. This is an electrophotographic toner containing a 2:1 type metal complex salt compound represented by ) as a charge control agent and a colorant. 2:1 of general formula (1) used in the toner of the present invention
The type metal complex salt compound has the general formula (2) (where R 1 and m are as defined previously.)
The diazo component represented by is diazotized by a conventional method, and this diazo compound is expressed by the following general formula (3). (In the formula, R 2 , R 3 , R 4 are as defined above.) By coupling according to a conventional method with the coupling component represented by the formula (4), the following general formula (4) is obtained. (wherein R 1 , R 2 , R 3 , R 4 , and m are as defined above, and Y represents an anion), and then this monoazo compound is Alternatively, it can be obtained by treatment with a chromation-imparting agent or a cobalt-imparting agent in an organic solvent by a conventional method. The complex salt compound according to the present invention obtained in this way has a positive chargeability, and contains resins (for example, monomers of styrene and its substituted products such as polystyrene and polyvinyltoluene, and styrene-substituted styrene copolymers). , styrene-acrylic ester copolymer, styrene-methacrylic ester copolymer, styrene-acrylonitrile copolymer,
Polyvinyl chloride, polyethylene, silicone resin, polyester, polyurethane, polyamide,
Epoxy resin, modified rosin, phenolic resin, etc. ), which is dispersed by kneading and further finely pulverized, also exhibits positive chargeability. Furthermore, this dye has good compatibility with the resins mentioned above and can be uniformly and finely dispersed in the resin. On the other hand, this complex salt compound had extremely low solubility in water, and therefore was not affected by environmental humidity and was able to maintain stable positive chargeability. The developing powder of the present invention is prepared by melting and blending the complex salt compound of formula (1) in a weight ratio of 1 to 50% based on the synthetic resin,
After solidification, the mixture is crushed with a ball mill or other crusher, or a polymerization initiator is added to the synthetic resin monomer, and the complex salt compound is added thereto in a weight ratio of 1 to 50% based on the monomer, and the mixture is immersed in water. It can be produced by polymerizing in suspension. At this time, other coloring agents or carbon black may be added in addition to the complex salt compound.
The developer powder produced in this way provides an amount of charge suitable for developing an electrostatic image through friction with the carrier, and the amount of charge remains constant even after repeated development, and the charge distribution is uniform. held constant. Therefore, images developed using this developing powder have uniform and constant density, and are much clearer than conventional positive developing powders. Hereinafter, the present invention will be explained in detail with reference to Examples.
In the examples, parts represent parts by weight. Example 1 Styrene-n is added to two parts of the metal complex compound represented by
- Add 100 parts of butyl methacrylate copolymer and 10 parts of carbon black, mix well, knead while heating and melting, and after cooling, coarsely crush with a mixer,
Then, it was pulverized using a high-speed centrifugal pulverizer to obtain a fine, positively charged toner. Add the above toner to a commercially available copier using a zinc oxide photoreceptor at a weight ratio of 5:100.
When mixed with iron powder with a diameter of 100 to 150 μm, clear images with no fog were obtained. The charge amount of the toner was measured using the blow-off method and was 17.6μC/g on average, and the charge distribution was 17.3μC/g.
It was almost uniform at ~18.0 μC/g. Examples 2 to 19 According to Example 1, toners containing a metal complex compound were obtained with the compositions shown in the following table. The charging characteristics of these toners are also summarized in the table.
