Toner and method for producing toner

A method for producing a toner, comprising the steps of:

• producing a toner base particle containing the wax and the resin component;
• and
• producing the toner particle by heat treatment of the toner base particle in the temperature range of TmA to TmW for 30 minutes or more, wherein TmW denotes the melting point of the wax, and TmA denotes the melting point of the vinyl polymer A, and
• the toner comprises a toner particle containing a resin component and a wax,
• wherein
• the resin component contains a vinyl polymer A having a monomer unit A represented by the formula (A):
• wherein R1 denotes H or CH3, and R2 denotes an alkyl group having 18 to 36 carbon atoms,
• in scanning transmission electron microscopy observation of a cross section of the toner particle, a backscattered electron image of the cross section of the toner particle is acquired, a luminance of each pixel constituting the backscattered electron image is assigned to one of 256 tones in the luminance range of 0 to 255, and a luminance histogram with a horizontal axis representing the luminance and a vertical axis representing a pixel value is created,
• a total pixel value C in the luminance range of 0 to 9 and a total pixel value A in the luminance range of 0 to 245 satisfy the formula (1):
• 0.000≤C/A≤0.250 (1)
• and when the pixel value in the luminance range of 10 to 245 in the histogram has a maximum value P at a luminance X, luminance M−luminance N ranges from 120 to 235, wherein the luminance M denotes a luminance at which the pixel value falls below 20% of the maximum value P for the first time from the luminance X to the luminance of 245, and the luminance N denotes a luminance at which the pixel value falls below 20% of the maximum value P for the first time from the luminance X to the luminance of 10.
