Apparatus and method of correcting color registration in electrophotographic printer

Disclosed are an apparatus for and a method of correction color registration in an electro-photographic printer. An apparatus for correcting color registration in an electro-photographic printer, in which exposure start points of each color unit for a photosensitive drum are adjusted to superpose images developed in a plurality of colors on matching positions of a transfer belt, includes an exposure unit to project light beams on the photosensitive drum to form latent images of one or more marks for each color unit. A developing unit is also disclosed to generate developed images by developing the latent images of the marks and a mark sensing unit is provided to detect the developed images transferred on a surface of the transfer belt for a predetermined time period. A color registration controller stores information on time points at which the developed images are detected and compares the number of the time points with the number of the marks. Thus, the color registration controller controls the exposure start points in response to the compared result.
