    摘要： A developing unit (210) includes a case which accommodates toner containing pigment, a developing roller (211), a supply roller (240) having chamfered ends and formed of an elastic member arranged to be pressed against a surface of the developing roller in such a manner as to supply toner to the surface of the developing roller. Moreover, the ratio or open cells in the elastic supply roller (240) is made to be 30% or higher and depth of engagement of the supply roller to the developing roller is made to be 0.4 mm or smaller. Also a first sealing member is disposed on the side ends of the developing roller and supply roller so as to prevent leakage to the outside portion of the case. The side surfaces of the developing roller have a surface roughness of 0.5 µm or smaller in Rmax. Further, a second sealing member in the form of a film is pressed against a lower surface of the developing roller in order to prevent leakage of toner, wherein a quantity δ of displacement of the sealing member due to its abutment against the developing roller satisfies 0.1 mm

    摘要： Described is an image forming apparatus comprising a transfer means which has a film (61) lightly contacting a back surface of a transfer medium and applying a transfer field thereto. The film (61) rises rapidly with respect to a contact portion (61a) with the back surface of the transfer medium on the upstream side (U) of the direction of movement of the transfer medium relative to the film (61), and slopes gently from the contact portion in a continuous curve (61c) on a downstream side (D) of the direction of movement. The film is capable of displacement between a support (63) and an image carrier, and contacts and disengages the transfer medium according to the presence or absence of electrostatic adsorptive force due to the supply or withdrawal of an electric current.
