PROBLEM TO BE SOLVED: To achieve a resolution equal to or more than an interval between light-emitting elements which are optically driven.SOLUTION: A method for forming an electrostatic latent image on a photoreceptor by optically controlling an LEDA print head 130 in which LED elements are arranged, by which image information concerning an image to be formed as an electrostatic latent image is acquired, a vibration element 140 for vibrating the LEDA print head 130 in a direction in which the LED elements are arranged is so controlled as to vibrate the LEDA print head 130, and lighting is controlled several times during a vibration period of the LEDA print head 130 on the basis of information in which pixels constituting said image information is extended in a sub-scanning direction.SELECTED DRAWING: Figure 6 【課題】発光駆動される発光素子の間隔以上の解像度を実現すること。【解決手段】ＬＥＤ素子が配列されたＬＥＤＡプリントヘッド１３０を発光制御することによって感光体上に静電潜像を形成する方法であって、静電潜像として形成すべき画像の情報である画像情報を取得し、ＬＥＤ素子が配列された方向にＬＥＤＡプリントヘッド１３０を振動させるための振動素子１４０を制御してＬＥＤＡプリントヘッド１３０を振動させ、画像情報を構成する画素の情報が副走査方向に拡張された情報に基づき、ＬＥＤＡプリントヘッド１３０の振動周期の間に複数回点灯制御することを特徴とする。【選択図】図６
