Abstract:
An image recording method in which when an image is recorded on one recording medium held on an external surface of a drum rotating at a first constant speed, said image being recorded by performing main scanning and exposure on said one recording medium with an optical system that uses a group of two-dimensionally disposed light source elements as well as by performing auxiliary scanning by moving said optical system in an auxiliary scanning direction that is substantially perpendicular to a main scanning direction, comprising the steps of:deflecting light from said group of two-dimensionally disposed light source elements to move the image formed on said one recording medium in accordance with a movement of said one recording medium, thereby having the image remain stationary relative to said one recording medium in the main scanning direction; moving said optical system at a second constant speed in the auxiliary scanning direction; and sequentially shifting modulation data of said group of two-dimensionally disposed light source elements in a direction opposite to the moving direction of the optical system in synchronism with a movement of the optical system in the auxiliary scanning direction, thereby having the image also remain stationary relative to said one recording medium in the auxiliary scanning direction.
