An exposure control for an imaging apparatus, the apparatus producing a light image based on an image member presented to the apparatus which is directed to a light responsive member via a partially silvered mirror of the apparatus. The exposure control includes a photocell which receives light transmitted through the mirror via a condensing lens, the photocell being connected to a circuit means which produces a signal having a duration, which varies according to the resistance of the photocell. The signal is used by a portion of the circuit means for controlling the exposure of the light responsive member to the light image.
