PURPOSE:To obtain a photographic image of a high quality, whose density is constant extending over the whole width, by constituting a destaticizing part of plural unit destaticizing elements, and plural destaticizing strength variable means for making a destaticizing strength of each unit destaticizing element variable at every unit destaticizing element of these elements. CONSTITUTION:In case when a black and white stripe-shaped uneven density has been detected in the width direction of a photosensitive drum 2 in a photographic character image which has been printed on a form 12, a destaticizing strength is varied by turning adjusting screws 84a-84h provided on the upper face of a case 81 of a destaticizing part 8 corresponding to a place where its eneven density has been generated, and varying a resistance value of variable resistances 87a-87h. The destaticizing part is divided into plural destaticizing lamps 83a-83h, and also the destaticizing strength of each destaticizing lamp can be adjusted by each adjusting screw 84a-84h, therefore, even if there is a difference of a photosensitivity in the width direction of the photosensitive drum 2, the difference of the photosensitivity can be corrected by setting a difference intentionally to the destaticizing strength of each place in the width direction. In this way, a photographic image of a high quality, whose density is constant extending over the whole width can be obtained. |
