PROBLEM TO BE SOLVED: To provide a screening conveyor equipped with a screening device capable of enhancing the ratio of separation and recovery of materials to be treated and also reducing equipment costs by saving the space for installation and the required output of a driving source. SOLUTION: In the course of conveying materials to be treated M by a conveyer belt 31 of a tilted belt conveyer 30, light materials to be treated on the conveyor belt 31 are floated in the upper layer by giving required vibration to the conveyer belt 31 caused by difference in level between the outer surface and projection parts 33b, 34b installed on the outer surface of vibrating rollers 33, 34. By the rotation of a rotary brush 41 installed on the downstream in the conveying direction of the vibrating roller 34, the light materials to be treated, which have been floated in the upper layer on the conveyer belt 31, is discharged from the conveyer belt 31 while scratched up by the brush hair 48.
