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.

摘要： A toner is comprised of a composition containing at least a polymer component and a charge control agent. The polymer component contains substantially no tetrahydrofuran (THF)-insoluble matter. The polymer component THF-soluble has a major peak and a minor peak in the specific molecular weight regions in gel permeation chromatography (GPC). The low molecular weight component and high molecular weight component of the polymer component, each of which shows the specific molecular weight region in GPC, have the specific acid values, respectively. The difference between the acid values is in the specific range.
