    摘要: An image forming apparatus includes an image carrier (40), an endless belt (10) whose front surface moves endlessly and contacts the image carrier to form a transfer nip, and a bias applying roller (62) configured to apply a transfer bias to a back surface of the endless belt. An image is formed of a toner having an additive embedded rate of not less than 40 percent. The toner includes a mother particle having a binder resin and a colorant, and an external additive. The bias applying roller (62) is located so as to satisfy a relationship, L > (A/2)+(B/2)+C, where A is a diameter of the image carrier (40), B is a diameter of the bias applying roller (62), C is a thickness of the endless belt (10), and L is a distance between centers of the image carrier and the bias applying roller, on a virtual plane perpendicular to an axis direction of the image carrier.

    摘要: An image forming apparatus includes an image bearing member (20Y), supporting rollers (15,16), a belt-like-shaped medium (10), a primary transfer member (12Y), a secondary transfer member (5), and a grounded conductive roller. The image bearing member forms a toner image at a predetermined process speed. The belt-like shaped medium has a charge voltage. The primary transfer member sequentially transfers the toner image onto the belt-like-shaped medium and the secondary transfer member transfers the toner image onto a recording sheet (2). The conductive roller is arranged in contact with the belt-like shaped medium by a predetermined wrapping length. A relationship Tb

    摘要: A multi-layer endless belt member (201), which is applicable to a transfer unit (200) for use in an image forming apparatus (1), includes a base layer (201b, 201d, 201f, 201j) and a surface layer (201a, 201c, 201e, 201g, 201h) disposed on the base layer and having a higher resistivity and has a first resistivity of a first surface thereof and a second resistivity of a second surface thereof opposite the first surface different from the first resistivity. The second resistivity of the second surface ranges from 9.0 to 12.5 in a common logarithm value (log[Ω/square]) when measured after 500V is applied for 10 seconds. An amount of resistivity change in the first resistivity ranges from 0.5 to 1.5 after application of 100V and is 0.2 or smaller after application of 500V. An amount of resistivity change in the second resistivity is 0.1 or smaller after application of 100V and 500V.
