PURPOSE:To prevent generation of copy dirt due to continuous copying by including at least one specified compound to a toner including at least resin and colorant. CONSTITUTION:To a toner for electrostatic charge development, comprising at least resin and colorant, at least one compound expressed by expression I or expression II is added. In the expressions I, II, R<1>, R<2>, Ar<1>, Ar<2> are substituted or not yet substituted alkyl group, or substituted or not yet substituted aralkyl group, A is titanium, zirconium, or silicon atom, and X is fluorine, chroline, or bromine atom. As examples of the substituted groups R<1>, R<2>, alkyl group such as methyl group, ethyl group, and stearyl group, or aralkyl group such as benzyl group are preferred, while, for Ar<1>, Ar<2>, alkyl group such as methyl group, ethyl group, or stearic group, and aralkyl group such as benzyl group are preferred respectively, and for X, fluorine atom is preferred. |
