Abstract
A sheet material feeder and an image forming apparatus in which, even when a sheet of thick paper is transported through a sharply curved sheet material guide, the sheet can be adjusted to a lateral registry position. A base plate, a movable lower guide and a movable upper guide can slide in a direction perpendicular to the direction of sheet transport in union with each other. Where a sheet material stopped at a lateral registry adjustment position is a sheet of thick paper, it is brought into a tightly stretching condition supported at three points, i.e., a crotch point of the movable upper guide, a top of the movable lower guide, and a guide surface of a regulation-side lateral register plate. The sheet material supported from both sides at the three points is moved together with the movable lower guide and the movable upper guide toward a reference-side lateral register plate for abutment against the same, whereby the lateral registry position adjustment of the sheet material is completed.
