摘要： A positively chargeable toner suitable to be carried on a cylindrical developer-carrying member having a resinous surface for developing an electrostatic latent image is formed from a composition including a binder resin, an imidazole compound and a colorant. The binder resin comprises at least one member selected from the group consisting of (i) a mixture of vinyl resin having a carboxyl group and a vinyl resin having a glycidyl group, (ii) a vinyl resin having both a carboxyl group and a glycidyl group, and (iii) a vinyl resin having a carboxyl group and a glycidyl group in a form reacted with each other. The imidazole compound is a compound having an imidazo unit represented by formula (1) below: wherein R1-R4 independently denote hydrogen or a substituent as specified. In some cases, two or more such imidazole units can be included in a combined form to provide the imidazole compound. The imidazole compound is effective for promoting a crosslinking reaction between the carboxyl group and the glycidyl group to provide the toner with improved fixability and anti-offset property in combination.

摘要： An electrophotographic toner is formed of a resinous composition including a binder resin and a wax (A). The wax (A) contains at least 92 wt. % thereof of n (normal)-paraffin comprising a plurality of n-paraffin species having different numbers of carbon atoms, and provides a DSC (differential scanning calorimetry)-heat-absorption curve exhibiting a maximum heat-absorption peak showing a peaktop temperature of 70-90° C. and a half-value width of at most 12° C. As a result of the n-paraffin-rich characteristic and the DSC-thermal characteristic, the wax can exhibit an improved fixability-improving effect without showing an excessive plasticizing effect, whereby the toner can exhibit good fixability as well as good flowability and storage stability.
