| titleOfInvention | Toner and developer for two-component magnetic developer |
| abstract | (57) [Summary] [Structure] The toner of the present invention is a negatively chargeable two-component magnetic developer toner in which carbon black is dispersed in a fixing resin medium and a charge control agent is not blended. As a fixing resin medium, a styrene acrylic copolymer resin or resin composition having a free or neutralized anionic polar group has an acid value of 4 to 30 when the anionic polar group is measured in the form of a free acid. And the number average molecular weight is 10 A resin containing 0.5 to 5 parts by weight of a polyethylene resin of 00 to 7000 per 100 parts by weight of the fixing resin medium is used, and the carbon black has a pH of less than 7 and (7-pH) / specific surface area ( m 2 / g) is 0.010 In the range of 0.05 to 0.05, the amount of 4 to 15% by weight based on the fixing resin medium is used. [Effect] It is possible to secure a sufficient amount of toner charge for development without blending with a negative charge control agent, and transfer of the charge control agent to the carrier surface and charge failure due to this spent are eliminated, and toner charge performance is improved. Can be stabilized over a long period of time, and the life of the toner and carrier can be extended. |
