TONER FOR DEVELOPING ELECTROSTATIC LATENT IMAGES

摘要

Toner for developing electrostatic images including core particles that contain a colorant, a binder resin, and a wax, and exhibiting low-temperature fixability, high-temperature anti-offset property, image durability, flowability, high-temperature preservability, and low particle emission rate.

主权项

1. A toner comprising core particles that contain a colorant, a binder resin, and a wax,
wherein two or more heat-absorption peaks due to melting of the wax are observed in a second scan of differential scanning calorimetry measurements on the toner, a main heat-absorption peak of the two or more heat-absorption peaks is present in a range of about 80° C. to about 100° C., a sub heat-absorption peak of the two or more heat-absorption peaks is present in a range of about 60° C. to about 80° C., a total area of the two or more heat-absorption peaks is in a range of about 1 J/g to about 10 J/g, and P2848/P1493, a ratio of P2848 and P1493 which are respectively peak intensities at 2848 cm−1 and 1493 cm−1 in a diffuse reflectance Fourier transform infrared spectrum of the toner, is in a range of about 0.45 to about 0.65.
