<p>PURPOSE:To provide a toner for developing an electrostatic charge image excellent in electrostatic charge stability and image stability, remarkably improved in the white ground stain (fog) of a copy and the scattering of the toner and having stable and high property of maintaining image density at low temp. and humidity. CONSTITUTION:This toner for developing an electrostatic charge image contains toner particles contg. at least a resin and a colorant and powder of a compd. represented by a formula M<1>y1.M<2>y<2>.M<3>x.(OH)2Ax/n.mH2O, wherein M<1> is at least one kind of divalent metal selected among Mg, Ca, Sr and Ba, M<2> is at least one kind of divalent metal selected among Zn, Cd, Pb and Sn, M<3> is a trivalent metal, A is an n-valent anion, 0<x<=0.5, y1 and y2 are positive numbers satisfying an equation y1+y2=1-x and 0<=m<2.</p> |
