Abstract
A transparent toner for forming a glossy surface is disclosed, wherein a critical surface tension of a glossy surface formed by the transparent toner at 20° C. is at least 50 mN/m, and the transparent toner comprises a resin composed of a polymer formed by employing at least a polymerizable monomer containing a carboxylic group (—COOH). An image forming method employing the transparent tone is also disclosed.
Claims4
An image forming method comprising at least steps of
- heating and melting a transparent toner supplied on an image support material;
- bringing the image support material, at a side on which the transparent toner is supplied, into contact with a belt;
- cooling the transparent toner while in contact with the belt;
- and
- releasing the image support material from the belt to form a glossy surface,
- wherein the transparent toner comprises a resin composed of a polymer formed by at least
- a polymerizable monomer containing a carboxylic group (—COOH),
- styrene, and
- an acrylic ester derivative or a methacrylic ester derivative,
- a content ratio of the polymerizable monomer containing the carboxylic group in the polymer is 15% by mass or more, and
- the glossy surface formed by the transparent toner has a critical surface tension, at 20° C., of at least 50 mN/m.
