An image forming apparatus comprising: a plurality of image forming units (13Y, 13C, 13M, 13BK), each of which has a photosensitive drum that has a rotational axis and is configured to be rotated in a prescribed rotational direction, the photosensitive drum supporting a toner image on a circumferential surface of the photosensitive drum, a charging unit configured to charge the circumferential surface, a developing unit configured to supply toner to the circumferential surface, and a static remover configured to emit charge-removing light on a portion on the circumferential surface, the portion being downstream of the developing unit in the rotational direction; a transfer belt configured so that it is brought into contact with a plurality of photosensitive drums of the plurality of image forming units (13Y, 13C, 13M, 13BK) and is rotationally driven so that the surface of the transfer belt moves in a prescribed movement direction and toner images are sequentially transferred to the surface, the transfer belt being an endless belt; and a plurality of transfer rollers (24Y, 24C, 24M, 24BK), each of which has a roller axis, are located so as to face the plurality of photosensitive drums with the transfer belt interposed between the plurality of transfer rollers (24Y, 24C, 24M, 24BK) and the plurality of photosensitive drums, and transfer the toner images to the transfer belt; wherein the image forming apparatus is further configured so that the static remover emits pre-transfer charge-removing light to a circumferential surface portion upstream of a position opposite to a position of the transfer roller in the rotational direction, and an amount of pre-transfer charge-removing light emitted to the circumferential surface by one static remover included in the plurality of image forming units (13Y, 13C, 13M, 13BK) is less than an amount of pre-transfer charge-removing light emitted to another circumferential surface by another static remover located upstream of the one static characterized in that in a cross section on which the rotational axis intersects, the roller axis of the transfer roller is located downstream of a straight line in the movement direction, the straight line passing through the rotational axis of the photosensitive drum that the transfer roller faces, and being orthogonal to a belt surface of the transfer belt; and in that a distance between the straight line and the roller axis of one transfer roller of the plurality of transfer rollers (24Y, 24C, 24M, 24BK) is greater than a distance between the straight line and the roller axis of another transfer roller located downstream of the one transfer roller in the movement direction. a plurality of image forming units (13Y, 13C, 13M, 13BK), each of which has a photosensitive drum that has a rotational axis and is configured to be rotated in a prescribed rotational direction, the photosensitive drum supporting a toner image on a circumferential surface of the photosensitive drum, a charging unit configured to charge the circumferential surface, a developing unit configured to supply toner to the circumferential surface, and a static remover configured to emit charge-removing light on a portion on the circumferential surface, the portion being downstream of the developing unit in the rotational direction;
