The image recording apparatus scans a heat mode recording material with a light beam modulated in accordance with image information, to thereby record an image on the heat mode recording material. The apparatus includes an unit for generating a modulated signal, an unit for generating an additional signal at a timing of at least one of rising and falling of the modulated signal and a unit for generating a drive signal by adding the additional signal to the modulated. The image forming method and apparatus scan a photosensitive material with the light beam to record an image, and a power of the light beam is set to a power of a level at which a recording line width or a recording dot size, which is determined depending upon a threshold value for the photosensitive material to blacken, is substantially fixed even if defocus occurs.

A light quantity adjusting method is used for driving a light emitting device with two drive current levels. The drive current levels are controlled by the first set data and the second set data, respectively. First, a resolution ratio and light quantity characteristics are stored. The resolution ratio represents a ratio between a drive current setting resolution of the first set data and a drive current setting resolution of the second set data. The light quantity characteristics represents a relationship between the first set data and a light emission quantity of the light emitting device. A value in the first set data is obtained as a first set value through adjustment for a quantity of light. Next, a change amount, from the first set value in the first set data is calculated using the light quantity characteristics. The calculated change amount is converted into a value in the second set data as a second set value using the resolution ratio.
