    摘要： In an image forming system, an image-bearing member having a photoconductor layer comprising an Si-based non-single crystal material is charged at a relatively low potential of 250 to 600 volts by a contact charging member in the presence of electroconductive fine powder. An electrostatic latent image formed on the image-bearing member is developed with a magnetic toner which includes magnetic toner particles comprising at least a binder resin and a magnetic iron oxide, and inorganic fine powder and electroconductive fine powder present at the surface of the magnetic toner particles. The magnetic toner has a weight-average particle size of 3 - 10 µm and an average circularity of 0.950 to 0.995, and contains 0.05 to 3.00 % of isolated iron-containing particles.

    摘要： A dry toner has toner particles containing at least a binder resin, a colorant and a wax component, and an external additive. The binder resin contains a component derived from a monomer selected from the group consisting of butadiene, isoprene and chloroprene. The toner has a main Tg of front 40°C to 70°C as measured by DSC. When specific surface area measured by the BET method when the toner is left for 72 hours in an environment of 23°C atmospheric temperature and 65% relative humidity is represented by A (m 2 /g) and specific surface area measured by the BET method when the toner is left for 72 hours in an environment of 50°C atmospheric temperature and 3% relative humidity is represented by B (m 2 /g), the toner satisfies the following relationship: 0.8 ≤ A ≤ 4.0, 0.80 ≤ (B/A) ≤ 1.05. In a toner's number-based circle-corresponding diameter/circularity scatter diagram as measured with a flow type particle image analyzer, the toner has a circle-corresponding number-average particle diameter D1 of from 2 to 10 µm and has an average circularity of from 0.950 to 0.995 and a circularity standard deviation of less than 0.040. The toner has, in its molecular-weight distribution of THF-soluble matter as measured by GPC, a main-peak molecular weight in the region of from 2,000 to 100,000 and contains a THF-insoluble matter in an amount of from 5 to 60% by weight.
