Title: Apparatus and method for forming image
Inventor: KODAMA KENICHI
IPC: B41J2/45
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for forming an image wherein visual conspicuousness of density variation is lowered and the image quality is improved even when there is an error of a feeding amount in a direction of intermittent and relative paper feeding. SOLUTION: Based on a frequency analysis of density variation due to the error of the feeding amount in a sub-scanning direction of an exposing head, intervals of LEDs in the sub-scanning direction in the exposing head in the image forming apparatus are made nonuniform so that the density variation occurs on an image in a high frequency wave region having a space frequency not less than 1 lp/mm. By using the image forming apparatus like the above, it is possible to form the image that the density variation is sufficiently suppressed in a low frequency region having a space frequency not greater than 1 lp/mm. Even when the density variation is comparatively great in the region having the high space frequency, the density variation can be visually observed by human eyes so that it is possible to improve the image quality.
