A method for forming an image in an electrophotographic printer. The method includes the steps of rotating a developing roller at the same linear velocity as that of a photosensitive medium in a state where the developing roller is separated from the photosensitive medium, moving a developer so that the developing roller is in contact with the photosensitive medium, and changing the linear velocity of the developing roller to be faster than that of the photosensitive medium after contact and proceeding with the developing process, rotating the developing roller at the same linear velocity as that of the photosensitive medium after completing the developing process, and moving the developer so that the developing roller is separated from the photosensitive medium. The linear velocity of the developing roller is equalized with that of the photosensitive drum whenever the developing roller is attached to or detached from the photosensitive medium, the toner supply to the photosensitive medium during development is sufficient, and shock caused by the attaching and detaching operation is alleviated, thereby greatly reducing the possibility of defective images.
