PROBLEM TO BE SOLVED: To provide an electrophotographic toner having a large saturated charge amount and excellent in image properties. SOLUTION: The electrophotographic toner contains a binder resin, a colorant and a clay-organic complex obtained by intercalating a quaternary ammonium salt represented by the formula (A): [(R<SP>1</SP>)<SB>3</SB>(R<SP>2</SP>)N]<SP>+</SP>X<SP>-</SP>into a smectite type clay, wherein R<SP>1</SP>and R<SP>2</SP>are different from each other, R<SP>1</SP>is a 4-24C alkyl, alkenyl or alkynyl, R<SP>2</SP>is a 1-10C alkyl, alkenyl or alkynyl; and X<SP>-</SP>denotes an anion.
