Abstract: In an image forming apparatus, a neutralizing portion provided on an image forming unit is configured to emit a neutralizing light toward a front irradiation position between a developing portion and a first transfer portion 15, on a photoconductor drum of an image forming unit, and a rear irradiation position between the first transfer portion and a cleaning portion, on the photoconductor drum of the image forming unit. A light quantity limiting portion is configured to limit an amount of light irradiated on the front irradiation position of the image forming unit, such that the amount of light is less than amounts of light irradiated on other front irradiation positions.

Abstract: A light guide member has a transmitting/reflecting portion transmitting and reflecting light that is emitted from a light source, to enter one end of the light guide member in a longitudinal direction, and be guided to the other end of the light guide member so that the light is applied to: a position between the developing roller and the transfer roller on the image carrier on a downstream side in the traveling direction of the transfer target member; and a position between the transfer roller and the cleaning portion on the image carrier on an upstream side in the traveling direction of the transfer target member. Furthermore, the light guide member has a convex portion having an arc-shaped cross section and being formed outward at a position opposing the transmitting/reflecting portion in a part of a predetermined specific region at one end or both ends in the longitudinal direction.

Abstract: In a light guide member included in an image forming apparatus, a transmitting/reflecting portion transmits and reflects light that is emitted from a light source to enter one end of the light guide member in a longitudinal direction and be guided to the other end thereof in the longitudinal direction. The light reflected by the transmitting/reflecting portion is emitted from a first optical surface. The light transmitted through the transmitting/reflecting portion is emitted from a second optical surface. At a cross section orthogonal to the longitudinal direction, a first outer peripheral surface has an arc shape including the first optical surface. Second outer peripheral surfaces expand from both ends of the first outer peripheral surface toward the second optical surface.

Abstract: A photosensitive member refreshing device includes an image bearing member, an exposure device, a developing device, a detecting section, a cleaning section, and a control section. The image bearing member has a photosensitive roller rotatable about a rotation axis. The exposure device exposes the photosensitive roller to light according to an exposure pattern. The developing device supplies a toner to the photosensitive roller to form a toner image corresponding to the exposure pattern on the photosensitive roller after the exposure device has exposed the photosensitive roller to light. The detecting section detects the toner image on the image bearing member. The cleaning section cleans a surface of the photosensitive roller. The control section controls the exposure pattern based on a result of detection by the detecting section.
