Hue modulating agent, developer and image forming method using said hue modulating agent

Abstract

To provide a toner for developing an electrostatic charge image which applied in image forming methods such as electronic photographic method, electrostatic recording method, electrostatic printing method, a developer which comprises the toner and the image forming method using the same. The toner in present invention contains at least a binder resin, colorant, an electrification controlling agent and wax (B), the electrification controlling agent consists of a zirconium-based compound (A) obtained from aromatic oxycarboxylic acids, derivatives of these or their salts and compounds containing zirconium or oxyzirconium. The weight proportion of the zirconium-based compound (A) to the wax (B) satisfies 3.0<=(A / B)100<=60.0. In this invention, a toner for developing an electrostatic charge image is provided with which an excellent image can be stably obtained even in a low temperature fixing process in long developer mixing time and multi thermal stress environments when low surface pressure roller is utilized.

Description

Technical field [0001] The present invention relates to a toner for developing electrostatic latent images used in image forming methods such as electrophotographic methods, electrostatic recording methods, and electrostatic printing methods, a developer containing the toner, and the use of the toner The image forming method. Background technique [0002] In the past, as an electrophotographic method, a photoconductive material is generally used to form an electrostatic latent image on a photoreceptor by various means, and then the latent image is developed with a toner, and the toner image is transferred to, for example, paper as needed. After that, it is fixed by heating and pressurizing or solvent vapor, etc. to obtain a copied image. [0003] As a method of heating and fixing the toner image on the transfer paper, from the viewpoint of its energy efficiency, a heating roller is generally used for fixing. In recent years, as energy saving progresses, a system that cuts off the...

Problems solved by technology

[0006] However, none of the above-mentioned various disclosed methods can satisfy both the effect on the problem of film formation and the effect on anti-sticking property.

[0007] Recently, copiers are often equipped with a printer function, and the output of only one copy or print is increased. Compared with the number of copies or prints, the stirring time of the developer is increased when developing.

In particular, in the mode of copying one document per document (commonly known as one-to-one copying, low-efficiency mode), it takes 2 to 8 times longer rotation time than the development rotation time of copying one copy in continuous copying.

In the case of the above mode, the following adverse effects are produced: when the developer is stirred, the thermal stress generated between the developer and the developer regulating member becomes larger, the toner is thermally bonded and solidified into a block, and moreover, the toner is easy to cover On the carrier, shorten the life of the toner, or form a film on the photoreceptor, etc.
