TONER, DEVELOPER, AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a toner excellent in transfer stability and filming resistance.SOLUTION: In a toner, inorganic particles adhere to the surface of a base particle. The base particle includes a binder resin and a colorant, and the inorganic particles include an adhering particle X having primary particles X adhering to each other and a primary particle Y. When an isolation rate of the inorganic particles separated by applying supersonic vibration for one minute in an output of 20 W and at a frequency of 20 kHz is represented as A [mass%], and an isolation rate of the inorganic particles separated by applying supersonic vibration for one minute in an output of 60 W and at a frequency of 20 kHz is represented as B [mass%], a formula 10≤A≤200≤B-A≤5 is satisfied.
