Abstract
An image forming method comprises the steps of providing pattern elementary marks which provide an image pattern, controlling the size of the pattern elementary marks, and forming the pattern elementary marks substantially at equal intervals. The controlling step is such that use is made preferentially of the pattern elementary marks in an area wherein the variation in density gradient level relative to the variation in size of the pattern elementary marks is great. An apparatus for carrying out such method is provided.
