Toner for forming electrostatic image, developer, process cartridge, and image forming apparatus
摘要:
To provide a toner, which contains a colorant, a binder resin, and a releasing agent, wherein the toner satisfies the following (a) to (c): (a) the toner contains at least a polyester resin as the binder resin; (b) the toner has Tg1st of 25° C. to 50° C.; and (c) the toner has a TMA compressive deformation rate (TMA %) of 10% or lower at 50° C. under a condition having relative humidity of 70%, wherein the Tg1st is glass transition temperature of the toner for first heating, as the toner is measured by a DSC system (a differential scanning calorimeter).
