摘要： An electrophotographic toner is prepared by using a binder resin having an acid value of 5 to 15 mgKOH/g, a salicylic metal complex, a colorant, and a releasing agent. In the preparation determination for the third root distribution of a light emission voltage by helium atmospheric pressure microwave induction plasmas for carbon atoms derived from the binder resin and metal atoms derived from the salicylic metal complex is made based on a value measured by a micro-particle measuring apparatus including a normal pressure or atmospheric pressure space, a capillary tube inserted at one end in the space, a microwave source, a cavity, a quartz tubular reactor, a discharge means, an analyses means, and a signal detection portion. The absolute deviation showing the scattering of approximate straight lines approximated by a least squares method is controlled to be 0.08 or less.

摘要： A binder resin as the main component of the toner has a low molecular weight polypropylene as a separating agent, encapsulated therein. Using this binder a toner with the wax having a diameter of 0.3 .mu.m or less dispersed therein is produced. The wax is included 0.5 part to 5 parts by weight for 100 parts by weight of the binder resin. This limitation of the toner prevents the setoff phenomenon during the fixing process and at the same time prevents the filming phenomenon over the photoreceptor and achieves an improved fixing performance.
