摘要

PROBLEM TO BE SOLVED: To provide a non-magnetic one-component toner that can discharge, even when recording sheets containing talc or calcium carbonate are used, the talc or calcium carbonate to be mixed into a developing machine to output images together with toner to provide stable images for a long period.SOLUTION: There is provided a non-magnetic one-component toner that contains toner base particles and at least two types of external additives and has a calcium carbonate emission rate of 0.8 or more, preferably, a chemical toner that contains the toner base particles having a volume average particle diameter of 3 to 10 μm and a shape factor SF of 110 to 135.
