Latest Patents
Yoshimura's latest patents include innovative methods for producing encapsulated toner for heat-and-pressure fixing. One patent details a method that involves forming a heat-fusible core material containing at least a thermoplastic resin and a shell. This shell is designed to coat the surfaces of the core material with an amorphous polyester through in situ polymerization. The process requires careful adjustment of the pH of the suspension during polymerization to a range of 9 to 13, with an acid value of the amorphous polyester ranging from 0.1 to 15 KOH mg/g.
Another patent focuses on a developer composition that includes a toner with a binder resin, a coloring agent, and a toner scum preventive. The binder resin is primarily a polyester resin or a resin produced by concurrently carrying out addition polymerization and condensation polymerization in one reaction vessel. This innovative toner prevents the formation of toner scum on the carrier surface, thereby extending the service life of the developer while maintaining low-temperature fixing ability.
