Abstract:
Toner particles contain a non-crystalline polyester resin, a crystalline polyester resin, a styrene-acrylic acid-based resin, and a releasing agent. An amount of the releasing agent contained in the toner is at least 7.5% by mass and no greater than 12.5% by mass. An amount of the styrene-acrylic acid-based resin contained in the toner is at least 50 parts by mass and no greater than 100 parts by mass relative to 100 parts by mass of the releasing agent. The crystalline polyester resin includes an acrylic acid-based unit and a styrene-based unit. The styrene-acrylic acid-based resin includes an acrylic acid-based unit that has an epoxy group and a styrene-based unit. A peak top molecular weight of the toner in a differential molecular weight distribution curve is at least 8,000 and no greater than 12,000. A mass average molecular weight of the toner is at least 40,000 and no greater than 65,000.

Claim (Index 1):
An electrostatic latent image developing toner comprising a plurality of toner particles each containing a non-crystalline polyester resin, a crystalline polyester resin, a styrene-acrylic acid-based resin, and a releasing agent, wherein\n an amount of the releasing agent contained in the toner is at least 7.5% by mass and no greater than 12.5% by mass, an amount of the styrene-acrylic acid-based resin contained in the toner is at least 50 parts by mass and no greater than 100 parts by mass relative to 100 parts by mass of the releasing agent, the crystalline polyester resin includes a first repeating unit derived from an acrylic acid-based monomer and a second repeating unit derived from a styrene-based monomer, the styrene-acrylic acid-based resin includes a third repeating unit derived from an acrylic acid-based monomer that has an epoxy group and a fourth repeating unit derived from a styrene-based monomer, a peak top molecular weight of the toner in a differential molecular weight distribution curve obtained by GPC measurement is at least 8,000 and no greater than 12,000, and a mass average molecular weight of the toner determined by the GPC measurement is at least 40,000 and no greater than 65,000.
