Abstract
The present invention provides a toner that exhibits excellent low-temperature fixing properties, offset resistance, and has excellent storage stability in a developing machine. The toner has, in a DSC curve obtained by measuring the toner with differential scanning calorimeter, a glass transition temperature (Tg) measured in a first scan of 50.0 to 70.0° C. and a temperature difference (Tg−Tg) between the glass transition temperature (Tg) measured in the first scan and a glass transition temperature (Tg) measured in a second scan ranging from 3.0 to 20.0° C.
