Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a toner not causing retransfer under various conditions of electric current for transfer and capable of repeatedly giving many high grade images. SOLUTION: This toner contains at least inorg. fine powder besides toner particles contg. at least a bonding resin and a colorant and has one or more heat absorption peaks by differential thermal analysis in a temp. range of =0.90 account for >=90number% of particles each having >=3μm particle diameter and particles each having a circularity (a) of >=0.98 account for
