Abstract: An object of the present invention is to suppress an influence due to temperature change and various aberrations. It is a projection lens which projects an image on a surface of a screen (magnified side). A first group I having a negative refractive power and a second group II having a positive refractive power are arranged in order from a magnified side toward a reduced side. The first group I is configured to arrange a first lens and a second lens in order from the magnified side, and the second group II is configured to arrange a third lens to a seventh lens. The first and second lenses are a negative meniscus lens whose both surfaces are formed by the aspherical surface in which an area near an optical axis of the surface on the magnified side is a concave surface. The third lens is a cemented lens in which a bi-concave lens is cemented to the surface on the reduced side of a bi-convex lens.

Abstract: An electrostatic latent image is formed on an image carrier. A first roller is opposed to the image carrier with a gap in between. A second roller is in contact with the first roller such that toner of a one-component type is supplied onto the image carrier by way of the first roller to develop the electrostatic latent image as a visible toner image. A single power source supplies a bias voltage in which an AC voltage is superposed on a DC bias voltage. The bias voltage is supplied to the first roller through a first path and to the second roller through a second path. A resistor is provided on the first path between the first roller and a branching point of the first path and the second path.

The inner surface of the light-shielding barrel is subjected to surface treatment so as to absorb unnecessary light thereby, reflect it thereat, or scatter it thereat. To be more specific, the light-shielding barrel has scattering grooves disposed on the inner surface thereof.
