Abstract
An image forming apparatus includes a transfer belt rotating in a rotational direction, photosensitive drums, primary transferring parts, static eliminating parts and cleaning parts. The static eliminating part is arranged between the primary transferring part and the cleaning part, and includes a light guide body and a light source arranged at one end side of the light guide body. The static eliminating part irradiates upstream and downstream sides from the light guide body in the rotational direction with the static eliminating light. The image forming apparatus comprises a first light shading part and/or a second light shading part. The first/second light shading part is arranged between the photosensitive drum at a downstream/upstream side from the light guide body in the rotational direction and the light guide body to adjust pre-transfer/post-transfer static eliminating light quantity from the light guide body to the downstream/upstream side photosensitive drum.
