<p>PURPOSE:To provide a toner compsn. for electrophotographic development having improved environmental stability. of a charged state without deteriorating the flowability of the toner. CONSTITUTION:Toner matrix particles are mixed with fine metal oxide particles of <=1.0mum average particle diameter with a complex formed on the surfaces as an additive to obtain a toner compsn. The complex is produced by bringing at least one kind of ligand selected among a mono- or polycyclic arom. diol deriv., a hydroxycarboxylic acid deriv. and a dicarboxylic acid deriv. into coordination with an atom of the metal of the metal oxide particles such as silicon dioxide as a central atom.</p> |
