An electrostatic image developing toner is disclosed. The toner particle conrains a silanol compound represented by formula of R_mSi(OH)_n in an amount of 1 to 20 ppm which is measured based on a head space method: wherein R represents a hydrocarbon group containing an alkyl group, a vinyl group, a glycidyloxy group, or a methacrylic acid, m and n each represents an integer of 1 to 3, and when m is 2 or 3, R may be the same of different.
