摘要：
A toner, wherein an amount of Al detected in the toner is 0.7% to 1.3%, where the amount of Al detected is determined based on quantitative analysis of Al by X-ray photoelectron spectroscopic analysis (XPS), and wherein [Tg2nd (THF insoluble matter)] is −40° C. to 30° C., where the [Tg2nd (THF insoluble matter)] is a glass transition temperature measured in second heating of differential scanning calorimetry (DSC) of THF insoluble matter of the toner.
