External additive for toner and toner

A toner comprising:

• a toner particle;
• and
• an external additive for toner comprising an external additive particle containing:
• a fine particle A;
• and
• a plurality of fine particles B that are each present so as to partially protrude from a surface of the fine particle A,
• wherein the fine particle A
• (i) is a particle of an organosilicon compound having a siloxane bond,
• (ii) has a number-average particle diameter of 0.03 μm or more and 0.30 μm or less, and
• (iii) has an average circularity of 0.90 or more,
• wherein, when the number-average particle diameter of the fine particle A is represented by DA, and a number-average particle diameter of the plurality of fine particles B is represented by DB, DB/DA is 0.10 or more and 0.63 or less,
• wherein the plurality of fine particles B have an average value of embedding ratios, each of which is defined by the following expression (1), of 30% or more and 80% or less, and
• wherein, when a projection image of the external additive particle is obtained, and a line that convexly closes the projection image is drawn, the line that convexly closes the projection image has a portion that overlaps a contour of the fine particle A,
• Embedding ratio (%) of fine particle B=(depth of fine particle B embedded in fine particle A/diameter of fine particle B)×100 (1)
