摘要:
An image formation apparatus having a cleaning process for removing defective toner from the developing unit during a non-image formation rotation of the photoreceptor drum. The image formation apparatus includes a reverse polarity charger for charging the photoreceptor drum to an opposite polarity from the polarity that is used for forming an electrostatic latent image. The reverse polarity charger allows defective toner to be removed from the surface of the photoreceptor during a warming-up process of the apparatus or after a predetermined number of image forming processes have been performed.

A lens diffusing light emitted from a light source includes a concave light-incident surface, a light guide portion, and a light-emitting surface. The light-incident surface includes a plane portion opposed to the light source and an optical function portion that is formed on the plane portion and one of scatters and diffuses the light. The light emitted from the light source enters the light-incident surface. The light that has entered the light-incident surface passes through the light guide portion. The light-emitting surface emits the light passed through the light guide portion.

The image forming portion of this image forming apparatus includes a LSU, a photosensitive drum, a developing unit holder, a multiple number of developing units, an intermediate transfer element, a transfer element and a fixing unit. All the developing units are of an identical configuration. Therefore, for replacement of developing units, the operator may and should remove any color of developing unit in the same fashion and attach a fresh developing unit of the color in the same fashion. The image forming portion sets up the image forming conditions for individual colors in the developing order.

The present invention is to provide a light-controlling film giving an excellent haze, and a compound and a composition which enable to produce the film. The invention provides phenyl acrylate represented by the formula (I); a composition comprising the phenyl acrylate and at least two kinds of compounds having a polymerizable carbon-carbon bond in a molecule; and a film obtained by photo-curing the above-mentioned composition. (wherein R represents a methyl group or a hydrogen atom.)

A lens diffusing light emitted from a light source includes a concave light-incident surface, a light guide portion, and a light-emitting surface. The light-incident surface includes a plane portion opposed to the light source and an optical function portion that is formed on the plane portion and one of scatters and diffuses the light. The light emitted from the light source enters the light-incident surface. The light that has entered the light-incident surface passes through the light guide portion. The light-emitting surface emits the light passed through the light guide portion.
