ABSTRACT:
The present invention provides a cyan toner including: one or plural heat-absorption peaks in a temperature range of 30 to 200° C. in a heat-absorption curve obtained by using a differential scanning calorimeter; a maximal value of a maximum heat-absorption peak temperature in the range of 65 to 150° C.; and a reflectance of 45 to 80% at a wavelength of 500 nm, a reflectance of 5 to 30% at a wavelength of 600 nm, and a brightness L* of 45 to 75, when measured in a powder form by spectroscopic analysis. The present invention thus provides a cyan toner capable of forming an image with reduced graininess and roughness from a low-density region to a high-density region and ensured a sufficient fixing temperature region, and a method for forming an image using the cyan toner.
