| abstract | PROBLEM TO BE SOLVED: To provide a toner which has good cleaning property even when a cleaning blade is set with a low contact pressure and can obtain a high-definition image. SOLUTION: Fine particles A and fine particles B are present on the surface of toner particles, the fine particles A are organosilicon polymer particles, and (i) the organosilicon polymer particles are represented by the formula (1). Has a T3 unit structure and has a T3 unit structure 29 In the Si-NMR measurement, the ratio of the silicon-derived peak area having the T3 unit structure is 0.50 or more and 1.00 or less, and (ii) the number average particle size da of the primary particles is 50 nm or more and 300 nm or less. The fine particles B have (i) a minimum ferret diameter of 150 nm or more and 300 nm or less observed by a scanning electron microscope (SEM), and (ii) an average value of consistency density of 0.45 or more and 0.90 or less. The relative permittivity of the fine particles A is ε ra and the relative permittivity of the fine particles B is ε rb , which satisfies the relationships of the equations (4) and (5). ε ra ≤ 3.5 equation (4) 0.5 ≤ ε rb −ε ra equation (5) [Selection diagram] None |
