An apparatus for recording an image, based on a pixel signal which has an on-mode or an off-mode signal, on a recording medium. The image is recorded by applying a threshold energy level, wherein the apparatus records a visible image if the pixel signal has the on-mode signal and does not record a visible image if the pixel signal has the off-mode signal. The apparatus includes a thermal head for recording the image, based on a first pixel signal, a second pixel signal and a third pixel signal, on the recording medium by applying the threshold energy level sequentially; a control circuit for generating first reference data in response to the mode of the second pixel signal and second reference data in response to the mode of the third pixel signal when the thermal head records the image based on the first pixel signal; and a driving circuit for controlling an energy level applied by the thermal head being below the threshold energy level, based on the combination of the first reference data and the second reference data generated by the control circuit when the thermal head records the image based on the first pixel signal which has the off-mode signal.
