发明名称 Electrostatic latent image developing magenta toner, electrostatic latent image developer, toner manufacturing method, and image forming method
摘要 An electrostatic latent image developing magenta toner includes at least quinacridone pigment, naphthol pigment, and a release agent. Colorant of the toner satisfies conditions (a) and (b): (a) an average primary particle size D50 of a quinacridone pigment represented by formula (1) and an average primary particle size D50 of a naphthol pigment represented by formula (2) are such that the average primary particle size D50 of the quinacridone pigment is smaller than the average primary particle size D50 of the naphthol pigment; and (b) the average primary particle size D50 of the quinacridone pigment is greater than 20 nm, and the average primary particle size D50 of the naphthol pigment is smaller than 200 nm. Formula (1): Here, each of R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3</SUB>, and R<SUB>4 </SUB>is selected from the group consisting of H, CH<SUB>3</SUB>, and Cl, R<SUB>1 </SUB>and R<SUB>2 </SUB>are different from each other, and R<SUB>3 </SUB>and R<SUB>4 </SUB>are different from each other. Formula (2):
