2. Description of the Related Art In a developing process, a developer used in an electronic copying machine or the like is once adhered to an image carrier such as a photoreceptor on which an electrostatic image is formed, and then is exposed to light in a transfer process. After being transferred from the body to the transfer paper, it is fixed on the copy paper surface in a fixing step. At that time, as a developer for developing the electrostatic image formed on the latent image holding surface, a two-component developer composed of a carrier and a toner and a one-component developer (magnetic toner) not requiring the carrier
It has been known.

By the way, one of the important characteristics required for the toner is charging property, and in particular, contact with the carrier or the container wall of the developing tank causes an appropriate level of positive or negative charging, and The charge level is required to be substantially stable over time even during continuous use or under adverse effects. The toner may be charged with a binder resin or a colorant itself, but it is difficult to obtain sufficient chargeability. Conventionally, as a substance that imparts chargeability to the toner (charge control agent), a positively chargeable nigrosine dye, a quaternary ammonium salt, a negatively chargeable metal-containing monoazo dye, a salicylic acid metal complex, a copper phthalocyanine pigment, etc. Has been known to be contained in toner.

However, these conventional charge control agents have some problems in terms of chargeability imparting effect and other required properties of toner. One of them is the safety of the toner. Most of the conventional charge control agents, particularly negative charge control agents, are for example the metal-containing dye types containing a metal such as chromium, because the applied charge level is high. However, as a component of the substance called toner, which is used very close to the human body,
It is preferable not to use a metal whose safety is doubtful, such as chromium. In recent years, in particular, the importance of such safety has been increasing, and the charge control of the toner, which does not contain a metal such as chromium as much as possible, has a better chargeability than before, and is excellent in other toner required characteristics. The development of agents is desired.

Further, the second problem of the toner is charging stability. Many conventional charge control agents have a high charge level but insufficient charge stability. For example, during continuous copying and continuous printing, the charge level changes over time, causing copy stains. Have the problem of doing. These problems tend to increase particularly in recent years with the demand for a copying machine or the like capable of continuously processing a large number of sheets at a high speed, and development of a charge control agent having more excellent charge stability is required. .

On the other hand, not only the charge control agent as described above, but also the improvement of the charge imparting property to the toner is caused by the conveyance, regulation, or friction of a carrier, a developing sleeve, a layer forming blade, etc. which come into contact with the toner during the developing process.

As the charge-imparting material, a material having a high durability against friction with the toner is required, and particularly, a material that can be used without changing the carrier for a long time is desirable.

The charge imparting material has the compound represented by the general formula (I) on at least a part of its surface. A coating solution obtained by dissolving or dispersing the charge control agent of the present invention in a solvent or a dispersion medium together with a binder resin, if necessary, is applied to the base material of the charge imparting material by dipping, spraying, brush coating or the like. Alternatively, when the base material is in the form of carrier particles, by a method of dipping and mixing this with the coating liquid and then drying, or a method such as coating with a fluidized bed of a direct mixture with the base material,
The charge-imparting material of the present invention can be obtained by forming a coating layer containing the charge control agent on the base material. Alternatively, a charge-imparting material may be obtained by directly melting and kneading the binder resin and the charge control agent and extruding and laminating the charge control agent on a base material. Further, the charge control agent may be contained in a moldable resin, and the charge control agent may be formed into a shape of carrier particles, a developing sleeve, or a layer forming blade to serve as a charge imparting material. The binder resin or molding resin is appropriately selected from those usually used, for example, polystyrene, polyacrylic acid ester,
