PROBLEM TO BE SOLVED: To provide a toner for electrophotography with which problems such as rediffusion, running, and sublimation have been solved, and fastness (light resistance) of the dye has been improved. SOLUTION: The toner for electrophotography containing at least one kind of metal-containing compound expressed by general Formula (1). It is all preferable that M in the general Formula (1) be Cu<SP>2+</SP>, that either R<SB>1</SB>or R<SB>2</SB>express an electron-attractant group, that the total ofσp values of R<SB>1</SB>and R<SB>2</SB>be 0.2-2.0, and that LogP of a single molecule of the ligand in the general Formula (1) be 3-8.
