Toner

A toner comprising a toner particle containing a binder resin and a release agent, wherein

• the toner particle has a surface layer that contains an organosilicon polymer;
• and
• for a luminance histogram, obtained by acquiring a backscattered electron image of a 1.5 μm-by-1.5 μm square of the surface of the toner particle in scanning electron microscopic observation of the toner particle surface, and classifying a luminance of each pixel constituting this backscattered electron image into 256 levels from a luminance of 0 to a luminance of 255, and moreover placing the luminance on an abscissa and the number of pixels on an ordinate in this luminance histogram,
• (i) two peak values P1 and P2 and a minimum value V between P1 and P2 are present, and the peak containing P2 is a peak originating from the organosilicon polymer,
• (ii) the luminance giving P1 is from 20 to 70,
• (iii) the luminance giving P2 is from 130 to 230,
• (iv) a percentage for P1 and a percentage for P2 with respect to the total number of pixels in the backscattered electron image are each at least 0.50%, and
• (v) formulas (1) and (2) below are satisfied
• (A1/AV)≥1.50 (1)
• (A2/AV)≥1.50 (2)
• where Bl is the luminance giving V, A1 is the total number of pixels in a luminance range from 0 to (Bl−30), AV is the total number of pixels in a luminance range from (Bl−29) to (B1+29), and A2 is the total number of pixels in a luminance range from (Bl+30) to 255.
