The binder resin is a polyester resin or vinyl resin respectively having an acid value of preferably 25-70 mgKOH/g. The long-chain compound is a long-chain alkyl alcohol having an OH value of 10-120 mgKOH/g or a long-chain alkyl carboxylic acid having an acid value of 5-120 mgKOH/g and is contained so as to satisfy a condition of the following formula (1) or formula (2): Formula (1) acid value of binder resin +OH value of long-chain alkyl alcohol >(¼)×OH value of binder resin, or Formula (2) acid value of binder resin +acid value of long-chain alkyl carboxylic acid >(¼)×OH value of binder resin. The toner is characterized by a good balance between fixing performances and developing performances suitable for a variety of models of image forming apparatus and in wide ranges of environmental conditions.

    摘要: A toner for developing an electrostatic image is formed as a mixture of toner particles containing at least a binder resin and a colorant, and inorganic fine powder. The inorganic fine powder includes: (A) inorganic fine powder (A) treated at least with silicone oil, and (B) inorganic fine powder (B) comprising a composite metal oxide including at least Si as a constituent element and having a weight-average particle size of 0.3-5 .mu.m. Because of the inclusion of the two types of inorganic fine powders (A) and (B), the toner is stably provided with a high flowability and a high triboelectric charge under various environmental conditions including low-humidity to high-humidity conditions. The toner is suitably used in an image forming system including a contact-charging means, a contact-transfer means and a film (or surf)-fixing system.
