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.
