    摘要: An electrophotographic toner composition suitable for heat-fixation and showing good storage characteristics is constituted by polymer components, a colorant and a metal-containing organic compound. The toner composition shows a melt index (at 125.degree. C., 10 kg-load) of 5-25 g/10 min., and the polymer components are characterized by (a) containing substantially no THF (tetrahydrofuran)-insoluble content, (b) including a THF-soluble content thereof providing a GPC (gel permeation chromatography) chromatogram showing i) a main peak in a molecular weight region of 2.times.10.sup.3 -3.times.10.sup.4, and a sub-peak or shoulder in a molecular weight region of at least 10.sup.5, and ii) an areal percentage of 3-10% in a molecular weight region of at least 10.sup.6, and (c) including a polymer component (H) in a molecular weight region of at least 10.sup.5 obtained by polymerization using a polyfunctional polymerization initiator and a monofunctional polymerization initiator.

    摘要: An image forming apparatus having a first image supporting member and an intermediate transfer member for transfer of an image from the first image supporting member and means for transferring the transferred image on the intermediate transfer member to a second image supporting member; characterized in that the contact angle between a surface of the intermediate transfer member and water is 60.degree. or above, and the sliding resistance of the surface is 200 g or below. The above image forming apparatus has excellent durability and good image forming properties under overall environmental conditions, and produces images without toner-filming.
