Abstract: An intake noise reduction device includes an air cleaner, an intake funnel and a resonator, and is connected to an engine via a throttle body. The resonator is provided inside of the air cleaner. The resonator includes a chamber portion and a pipe portion. The pipe portion is formed to extend downward from the chamber portion, and has an opening end at a lower end. The intake funnel is provided at a lower end of the air cleaner. An opening end of the resonator is inserted into the intake funnel. A cross sectional area of an intake passage between the intake funnel and the pipe portion is set to not less than an opening area of an intake passage of the throttle body opened to a maximum throttle opening.

Abstract: An electrophotographic method in which an electrostatic latent image on a single-layer organic photosensitive material is developed while applying a developing bias voltage of the same polarity as the polarity of the charge of the photosensitive material. The developing bias voltage is set to be higher than a potential that corresponds to a point where a curve approximating the zone of a large amount of exposure to light and a curve approximating the zone of a small amount of exposure to light in a light decay characteristics curve intersect each other.

Abstract: An image forming apparatus includes a rotatable photosensitive member including a conductive base and a photosensitive layer located on a surface of the base; a charging device located in the vicinity of the photosensitive member for charging the photosensitive layer; a charge removing device located upstream with respect to the charging device in a rotation direction of the photosensitive member for radiating light toward the photosensitive layer prior to charging performed by the charging device to uniformize a surface potential of the photosensitive layer; a light radiation device for radiating light to a charging area of the photosensitive layer in the state of being charged by the charging device and for adjusting the amount of the light to be radiated; an exposing device for radiating light corresponding to an image toward the photosensitive layer in the state of being charged; a developing device located downstream with respect to the exposing device in the rotation direction of the photosensitive memb

Abstract: An image forming apparatus includes a charge removing device for removing the residual charge on a photosensitive film. The light emitted from an optical source of the charge removing device is selected from the range between the wavelengths which correspond to half of the maximum absorbance in a light absorbance characteristic of the photosensitive film. Since carrier generation does not occur by the light emitted by the charge removing device, the charging ability and the charge retaining ability of the photosensitive film are improved, and the image quality is significantly improved.
