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.
Claims5
An image forming apparatus, comprising:
- three image forming units juxtaposed along a running direction of an intermediate transfer member, each of the three image forming units including a drum-like image carrier, and a developing portion, a transfer portion, and a cleaning portion sequentially disposed in a rotational direction of the drum-like image carrier, wherein
- the three image forming units are a first image forming unit for forming a black toner image on the intermediate transfer member, provided downstream in the running direction, a second image forming unit for forming a chromatic color toner image on the intermediate transfer member, provided further upstream than the first image forming unit in the running direction, and a third image forming unit provided in such a way that the second image forming unit is positioned between the first image forming unit and the third image forming unit, wherein
- the first image forming unit includes a first image carrier, a first developing portion, and a first transfer portion,
- the second image forming unit includes a second image carrier, a second developing portion, a second transfer portion, and a second cleaning portion, and
- the third image forming unit includes a third image carrier, a third transfer portion, and a third cleaning portion;
- a first neutralizing portion configured to emit a neutralizing light toward a first irradiation position on the first image carrier between the first developing portion and the first transfer portion, and a second irradiation position on the second image carrier between the second transfer portion and the second cleaning portion;
- a second neutralizing portion configured to emit a neutralizing light toward a third irradiation position on the second image carrier between the second developing portion and the second transfer portion, and a fourth irradiation position on the third image carrier between the third transfer portion and the third cleaning portion;
- and
- a light quantity limiting portion configured to limit an amount of light irradiated on the first irradiation position, such that the amount of light is less than another amount of light irradiated on the third irradiation position.
