Title:
TONER AND METHOD FOR MANUFACTURING TONER
Document Type and Number:
Japanese Patent JP2022094915
Kind Code:
A
Abstract:
To provide a toner that can have excellent low-temperature fixability, heat-resistant storage property, and mold releasability, and can have excellent durability.SOLUTION: A toner has a toner particle containing a resin component and wax. The resin component contains a vinyl polymer A having a monomer unit A represented by the formula (A). When a luminance histogram is obtained from STEM observation of a cross section of the toner particle, and when the total number of pixels from the luminance 0 to the luminance 9 is C and the total number of pixels from the luminance 0 to the luminance 245 is A, C and A satisfy the formula (1). When a luminance X is a luminance indicating the maximum value of the number of pixels P within a range from the luminance 10 to the luminance 245, a luminance M is a luminance when the number of pixels falls below 20% of P for the first time from the luminance X toward the luminance 245, and a luminance N is a luminance when the number of pixels falls below 20% of P for the first time from the luminance X toward the luminance 10, the value of the luminance M-the luminance N is 120-235.SELECTED DRAWING: None
