    摘要： The invention provides a toner which is excellent in its low-temperature fixing property and high-temperature offset resistance regardless of the types of paper, and constantly provides high-quality images regardless of environments and does not generate image defects even after prolonged use. In a master curve of the toner at a reference temperature of 150°C, a difference between a storage modulus at a frequency of 0.1 Hz and a storage modulus at a frequency of 1000 Hz is set in a rage from 0 to 2.5 × 10 5 Pa, where the activation energy determined from a shift factor is brought to a range from 50 to 130 kJ/mol.

    摘要： A toner with good low-temperature fixability even in light-pressure type fixing units, which causes no contamination of fixing films and provides images having stable image densities and excellent image quality after long-term use. The toner includes a toner particle containing a binder resin, a coloring agent, a release agents (a) and (b) The release agent (a) is a monofunctional or bifunctional ester wax; the release agent (b) is a hydrocarbon wax; a solubility of the release agent (a) into the binder resin is higher than that of the release agent (b). When tetrahydrofuran-soluble components of the toner are subjected to GPC, a proportion of components having a molecular weight of 500 or less is 2.5 area % or less. When the tetrahydrofuran-soluble components at 25° C. are subjected to SEC-MALLS, a weight-average molecular weight Mw thereof is 5,000-100,000, and the Mw and the radius of gyration Rw thereof satisfy 5.0×10−4≦̸Rw/Mw≦̸1.0×10−2.
