ABSTRACT:
There are disclosed a toner for development of an electrostatic image which comprises containing (a) a mixture of a lower molecular weight polymer component and a higher molecular weight polymer component, and said lower molecular polymer component is a resin obtained by reacting a polymer containing a carboxylic acid component with a polyvalent metal compound to form cross-linking through a metal atom and (b) offset preventive agent; and also an electrostatic latent image developer which comprises (A) toner particles mainly comprising a resin obtained by reacting a carboxy group existing in a polymer component with a polyvalent metal compound and (B) resin coated-carrier particles coated with a fluorine-containing resin on a surface of a magnetic particle or inorganic fine particles.
