Abstract: A positively chargeable toner comprising a resin binder, a specified compound represented by the formula (I), and a higher fatty acid with a long-chain alkyl group having 8 to 22 carbon atoms and/or a metal salt thereof. The positively chargeable toner is a positively chargeable toner used for the development of a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method or the like.

Abstract: The present invention describes a process for preparing a toner mixture comprising mixing a first toner with at least one further toner wherein the first toner has an acid value of from 0.1 to 30 mgKOH/g and comprises at least one binder resin and at least one coloring agent wherein said binder comprises as the main component a polyester resin and wherein the further toners comprise at least a binder resin and optionally at least one coloring agent. It also describes a developer composition comprising said toner mixture and optionally a carrier. The new toner mixture does not show any de-mixing phenomenon during repeated use.
