Abstract
PURPOSE:To improve the gradation of a half tone image part without deteriorating the reproductivity of a character part by executing a process for altering an electrification state only in a specified area of electrostatic latent image. CONSTITUTION:The process for altering the electrification state is executed to the electrostatic latent image formed on a photosensitive body 8 according to the kind of an original 1. Namely, by making the respective LEDs 13a, 13b... of a fine density LED array 13 in an on-state and off-state every other pitch in the half tone image areas P and R and rotating the photosensitive body 8, for example, exposure is executed in slit shapes and the electrostatic latent image is finely divided. In character image areas Q and S, the exposure in slit shapes is not executed and the electrostatic latent image formed with an image light from the original 1 is developed, as it is. Thus, the gradation can be made favorable as for the half tone image area and also the deterioration in the reproductivity of the character can be prevented as for the character image area.
