Abstract

An image recorder capable of recording an image by a predetermined line width with no regard to the operating conditions and ambient conditions by causing the line width of an image into coincidence with a predetermined referece line width. A driver controllably drives an exposing device in response to optical data. A line width sensor means the line width of a visible image developed by a developing device. Control means controls, in response to the line width sensed by the sensor, the driver such that the line width coincides with a predetermined reference line width, and corrects the controllable drive of the exposing device by the driver.
