A paper feeder, a control method thereof, and an image forming apparatus having the same are provided. The paper feeder includes a moving member to push paper loaded on one paper loader to another empty paper loader. With regard to operation of the moving member, the stop time of the moving member may be variable based on a paper size input by a user, which enables a stop position of the moving member to be automatically adjusted based on the paper size, resulting in enhanced user convenience.

To restrict a period velocity change of a photoconductor that is an immediate cause of a color registration error, a gap change of a color registration error detection pattern caused by a linear velocity change of the photoconductor is acquired and a linear velocity change of the photoconductor is reduced based on a relationship between the gap change and a velocity of a motor, whereby a reduced color registration error is accomplished.

Image forming apparatus and control method thereof
