    2007
    Co-Authors: Sasaki Yuki, Matsuoka Hirotaka, Mera Fumiaki, Hiraoka Satoshi, Matsumura Yasuo
    Abstract:

    PROBLEM TO BE SOLVED: To provide a Broensted acid compound improving especially surface activity and imparting high reactivity by using a small amount even at low temperatures as an acid catalyst in an alkylbenzenesulfonic acid used as a surfactant and a Broensted acid, to provide a method for producing the condensed compound and a method for producing a binding Resin using the same, to provide a condensed compound Particle dispersion produced by the condensed compound, to provide a Resin Particle dispersion produced by the binding Resin, to provide an electrostatically charged image developing toner and an electrostatically charged image developer produced by using the same and to provide a method for forming an image. SOLUTION: The Broensted acid compound is characterized in that the Broensted acid compound is a compound represented by formula (I) (wherein, R HL represents a Cl or an F; R 1 represents an 8-20C alkyl group; and n represents an integer of 1-4).

  • Resin Particle dispersion electrostatically charged image developing toner method for producing them developer and method for forming image
    2007
    Co-Authors: Matsuoka Hirotaka, Sasaki Yuki, Mera Fumiaki, Hiraoka Satoshi, Matsumura Yasuo
    Abstract:

    PROBLEM TO BE SOLVED: To provide a Resin Particle dispersion having stably dispersed Resin Particles in an aqueous medium by a low energy, a method for producing the same, an electrostatically charged image-developing toner sufficiently satisfying toner characteristics by using the Resin Particle dispersion, a method for producing the same, an electrostatically charged image-developer and a method for forming the image. SOLUTION: This Resin Particle dispersion obtained by dispersing Resin Particles containing at least a polycondensate Resin obtained by performing the polycondensation of a polycondensable monomer in an organic solvent is characterized with that the polycondensate Resin has ≥1 aromatic ring and/or alicyclic ring in its recurring unit, and the median diameter of the Resin Particles is ≥0.05 and ≤2.0 μm. The method for producing the same, the electrostatically charged image-developing toner by using the Resin Particle dispersion, the method for producing the same, the electrostatically charged image-developer and the method for forming the image are also provided.
