Image forming apparatus with skew correction
 An image forming apparatus for forming an image on a recording material. The position of the recording material is detected when the recording material is underway from a registration roller for correcting a skew of the recording material to an image forming position for the recording material, and the image is written based on the detected position signal. The image is thus formed at a proper position on the recording material.
