Conveyor system and image forming apparatus including same

A conveyor system includes a first conveyor belt (61) entrained about a separation roller (63) and a support roller (62) disposed upstream from the separation roller (63), a second conveyor belt (17) entrained about a first roller (17A) disposed at an uppermost stream in a transport direction of a sheet-type medium and a second roller disposed downstream therefrom, a belt alignment device (70) to tilt a rotary shaft (63a) of the separation roller (63) to restrict a range of belt mistracking of the first conveyor belt (61) in a width direction thereof within a predetermined range, and a restriction member (72a, 68b) to restrict an amount of inclination of the rotary shaft (63a) such that a hypothetical extended plane (A), which is a hypothetical extension of the outer circumferential surface of the first conveyor belt (61) between the separation roller (63) and the support roller (62) to a downstream side in the transport direction, does not contact a rotational center axis of the first roller (17A).
