Title:

TONER, IMAGE FORMING APPARATUS, AND TONER STORED UNIT

Document Type and Number:

WIPO Patent Application WO/2016/170730

Kind Code:

A1

Abstract:

A toner, where a diffraction peak of the toner as measured by X-ray diffraction spectroscopy is present at least in a region where 2θ is from 20° through 25°, and a difference between Tg1 and Tg2 is 10°C or less, where Tg1 is a glass transition temperature of the toner, as observed in a last heating step, when heating and cooling are performed on the toner by means of a differential scanning calorimeter (DSC) under the heating and cooling conditions 1 defined in the specification, and Tg2 is a glass transition temperature of the toner, as observed in a last heating step, when heating and cooling are performed on the toner by means of the differential scanning calorimeter (DSC) under the heating and cooling conditions 2 defined in the specification.
