(G'.sub.80) providing a ratio (G'.sub.60 /G'.sub.80) of at least 80, and a storage modulus at 155.degree. C. (G'.sub.155) and a storage modulus at 190.degree. C. (G'.sub.190) providing a ratio (G'.sub.155 /G'.sub.190) of 0.95-5. As a result, the toner shows good low-temperature fixability and anti-offset characteristic, and also little temperature-dependence of gloss.

    摘要： An electrophotographic toner showing a good fixability onto recording paper is constituted by at least a binder resin and a colorant, the binder resin comprising a resin component having a polar group, the binder resin having a molecular weight distribution according to gel permeation chromatography including a peak in a molecular weight region of 5.times.10.sup.3 -5.times.10.sup.4. The toner is used to develop an electrostatic image formed on a electrophotographic photosensitive member including at least an electroconductive support, a charge generation layer and a charge transport layer, and the resultant toner image is transferred onto a recording medium without difficulties such as occurrence of cracks on the photosensitive member or inferior transferability by using a photosensitive member having a surface layer containing a transition metal atom at 0.1-10 ppm. The surface of the photosensitive member may preferably show a fluorine atom/carbon atom (F/C) ratio or/and a silicon atom/carbon atom (Si/C) ratio, respectively, of 0.03-1.0 as measured by X-ray photoelectron spectroscopy.

    摘要： An electrophotographic toner is formed of toner particles each comprising at least a binder resin, a colorant and a release agent, and a low-crystalline aromatic metal compound present at surfaces of the toner particles. The toner has an average circularity of at least 0.955, and the low-crystalline aromatic metal compound has an X-ray diffraction characteristic free from peaks exhibiting a measurement intensity of at least 10000 cps and a half-value half-width of at most 0.3 deg. in a range of measurement angles 2&thgr; of 6 to 40 deg. Because of the low crystallinity, the aromatic metal compound is uniformly applied onto the toner particle surfaces to stabilize the chargeability and transferability of the toner.
