Abstract:
A toner comprising a toner particle that contains a binder resin and a release agent, wherein the toner particle has a surface layer that contains an organosilicon polymer and the luminance histogram of a backscattered electron image of the toner particle has two peak values P1 and P2 and a minimum value V between P1 and P2, P2 originates from the organosilicon polymer, and the luminance giving P1 and P2 are in specific ranges, percentages for P1 and P2 are each at least 0.50%, and using the luminance Bl at V as a reference point, specific relationships are satisfied by A1, AV, and A2, where A1 is the total number of pixels at luminance from 0 to (Bl−30), AV is the total number of pixels at luminance from (Bl−29) to (Bl+29), and A2 is the total number of pixels at luminance from (Bl+30) to 255.

Claim (Index 1):
A toner comprising a toner particle containing a binder resin and a release agent, wherein\n 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 \u03bcm-by-1.5 \u03bcm 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\n ( A 1/ AV )\u22651.50\u2003\u2003(1) \n ( A 2/ AV )\u22651.50\u2003\u2003(2) \n where Bl is the luminance giving V, A1 is the total number of pixels in a luminance range from 0 to (Bl\u221230), AV is the total number of pixels in a luminance range from (Bl\u221229) to (Bl+29), and A2 is the total number of pixels in a luminance range from (Bl+30) to 255.
