摘要： A toner for developing an electrostatic image is constituted by toner particles containing at least a binder resin and a colorant, and particles containing at least one double oxide. The double oxide includes a double oxide (A) represented by the following formula (1):M.sub.a Si.sub.b O.sub.c (1),wherein M denotes a metallic element selected from the group consisting of Sr, Mg, Zn, Co, Mn and Ce; a is an integer of 1-9; b is an integer of 1-9; and c is an integer of 3-9. The above particles including a double oxide (A) are effective in improving flowability and triboelectric chargeability of the toner and providing a resultant image with excellent image qualities.
