Publication number: 20030207190Abstract: Disclosed is an electrophotographic toner which comprises a bisphenol A monomer. The toner may be either a magnetic toner or a non-magnetic toner, and the developing method using the toner may be either a single-component developing method or a two-component developing method. Moreover, the toner can be used commonly with both the flash fixing system and the heat roll fixing system and significantly improves the fixing strength without accompanying any prior art problem such as formation of voids during fixing.Type: ApplicationFiled: October 2, 2001Publication date: November 6, 2003Applicant: Fujitsu LimitedInventors: Yasushige Nakamura, Toru Takahashi

Publication number: 20030207191Abstract: In a toner T of the present invention, the liberated mother particle ratio is set to be 10% or less and the liberated silica particle ratio is set to be 0.2-10%, thereby reducing the possibility that the liberated mother particles 18′ and the mother particles 18 with silica particles 19 therein will be fused on toner-contact members such as a latent image carrier, a toner carrier, and a toner regulating member, and thus effectively preventing the filming of toner T. Therefore, according to the toner T of the present invention, the durability of the toner-contact members such as the latent image carrier, the toner carrier, and the toner regulating member can be improved.Type: ApplicationFiled: December 28, 2001Publication date: November 6, 2003Applicant: SEIKO EPSON CORPORATIONInventor: Takuya Kadota
