A two-component developer achieves development by attaching charged toner to an electrostatic latent image through friction with a carrier. Among component-based developers, toners that are charged by friction with brush-, strip-, or plate-shaped friction members that have the same function as carriers are known. Toner is known to be kept in a dispersed state and charged by mutual PJ rubbing with the magnetic fine powder. Therefore, these developing toners maintain a positive or negative charge depending on the polarity of the electrostatic latent image to be developed.

In order to cause the toner to retain the electric charge, it has been proposed to utilize the triboelectricity of resin, which is the main component of the toner, but this method requires that the toner has a small chargeability and
Since the solid surface resistance value is large, the obtained image tends to be fogged and becomes unclear. In addition, some resins have certain functional groups introduced to them in order to retain a positive charge, but these functional groups may generate unpleasant odors during heat fixing.
The drawback is that the amount of charge varies widely. Therefore, in order to impart the desired triboelectric charging properties to the toner, a dye is used that imparts a charge.

[Problems to be Solved by the Invention] However, most of the above-mentioned charge control agents that have been put into practical use are colored and are therefore suitable for black toner compositions, but are not suitable for color toner compositions. The quaternary ammonium salts that are not suitable and are offered as black charge control agents are water soluble and difficult to uniformly disperse in toners, resulting in non-uniform charge transfer. Moreover, even if the toner has high chargeability at the initial stage of developer preparation, it decays exponentially depending on the storage conditions, and the decay is particularly large when the temperature and humidity are high. be.

[Effects of the Invention] As described above, the toner of the present invention containing the salt-forming compound represented by the general formula [11] as a charge control agent has a uniform am charge amount between toner particles, and the charge amount can be easily controlled. be. In addition, it is an extremely stable toner that does not change in quality during use and cause the amount of frictional charge to vary or decrease.
This toner exhibits unprecedented durability under various environmental conditions and can withstand long-term storage, and also has excellent abrasion resistance, fixing properties, and adhesion properties of toner images.
