Abstract: Provided is a film-forming toner excellent in grindability hand having a sufficient negative chargeability, and facilitate grinding performed in the manufacture. The film-forming toner contains a main resin, and a low-molecular-weight resin having a weight-average molecular weight lower than that of the main resin. The low-molecular-weight resin is one or more resins selected from terpene resins, alicyclic hydrocarbon resins, α-methylpolystyrene, modified rosin, novolak resins, modified novolak resins, aliphatic hydrocarbon resins, aromatic hydrocarbon resins, copolymerized resins of these resins, esterified modified rosin, a coumarone resin, C5 and C9 petroleum resins, and derivatives thereof. A proportion of the low-molecular-weight resin in the film-forming toner is 5 to 40 mass %. The film-forming toner has an average particle diameter D50 (volume) of 9 to 50 μm.

Abstract: A toner for a thermal transfer printing sheet is advantageous in terms of a fixing property to a release sheet, durability against deformation upon cooling, and a property of holding an image-forming toner, in addition to grindability and chargeability of the toner. The toner for a thermal transfer printing sheet is characterized by comprising a negative-charged crystalline polyester resin, wherein the toner has an average particle size D50 (volume) of 20 to 50 μm.
