Image forming apparatus

摘要

An image forming apparatus of a static exposure type uses a static exposure-type optical system to expose a photosensitive sheet to form a latent image thereon such that a visible image is produced from such a latent image. An exposure detector detects the amount of light energy to which the photosensitive sheet is exposed and the exposure of the photosensitive sheet to image forming light is continued by a control device until the cumulative light energy as measured by the exposure detector reaches a preset value.
