Abstract: A toner comprising a toner particle comprising a binder resin and a wax, wherein the binder resin comprises an amorphous polyester resin and a polymer A, contents of the amorphous polyester resin and the polymer A in the binder resin are within specific ranges, the polymer A comprises a first monomer unit in which ester (meth)acrylates comprising 18 to 36 carbon atoms are polymerized, a content ratio of the first monomer unit in the polymer A is within specific range, the toner comprises a matrix-domain structure comprising a matrix comprising the amorphous polyester resin and domains, and the domains comprise a domain A comprising at least 80 mass % of the polymer A and a domain B comprising at least 80 mass % of the wax.

Abstract: There is provided a resin magnet material that has excellent flame retardancy, produces only a small amount of toxic substances when ignited, and yields very few molding defects; as well as an electron beam adjustment apparatus in which this resin magnet material is used. To achieve this object, a first invention comprises a flame-retardant resin magnet material obtained by adding (Z) an alnico-based magnetic powder or a ferrite-based magnetic powder to a flame-retardant resin composition that is itself obtained by adding heat-resistant aluminum hydroxide and antimony trioxide to a polyamide resin in the following amounts: (A) per 100 weight parts polyamide resin, (B) X1 weight parts heat-resistant aluminum hydroxide with a decomposition temperature of 280° C. or higher (where 10 weight parts<X1<70 weight parts), and (C) X2 weight: parts antimony trioxide (where 40 weight parts<X2<270 weight parts).

Abstract: Provided are non-halogen, flame-resistant, resin materials and resin magnet materials, and also electron beam controllers comprising the resin magnet materials. The resin material comprises (A) a non-halogen resin composition, (B) a metal oxide hydrate, and (C) one or both of antimony trioxide and zinc borate. The resin magnet material comprises those components (A), (B) and C), and (D) a magnetic material. In the electron beam controller, the four-pole and 6-pole convergence magnets and the two-pole purity controller magnets are made of the resin magnet materials.
