Abstract
An image forming apparatus and a method of controlling the same capable of obtaining the same effect as when sheets of paper are picked up in such a state that front ends thereof are all aligned by controlling paper feeding based on results of detecting paper movement and capable of improving feeding speed by maintaining a time taken for the sheet of paper to move to a feed roller constant are provided. The apparatus includes a pick-up roller to pick up a sheet of paper, a forward roller to feed the picked-up sheet of paper toward a downstream side of a paper moving path, a feed roller to feed the sheet of paper fed by the forward roller toward the downstream side of the paper moving path, and a feed sensor mounted between the forward roller and the feed roller to detect movement of the sheet of paper.
