| description | To provide toner which can achieve both of the low-temperature fixability and the heat-resistant storage property, suppress contamination of a cleaning member and a photoreceptor, and has the excellent charging stability.SOLUTION: Toner has an inorganic external additive on a toner base particle surface containing at least a resin, a coloring agent and wax. When an isolation rate of inorganic particles isolated by the application of ultrasonic vibration for one minute at an output of 20 W and a frequency of 20 kHz in the inorganic particles contained in the toner is A [mass%], and an isolation rate of inorganic particles isolated by the application of ultrasonic vibration for one minute at an output of 60 W and a frequency of 20 kHz is B [mass%], 20 |
