Method for developing static latent image

The invention relates to a method for developing a static latent image. In the method, a compound magnetic toner is used, wherein the compound magnetic toner consists of 65 percent by weight of magnetic toner A and 34 percent by weight of magnetic toner B; the magnetic toner A contains an electrified charge inhibitor of which the polarity is opposite to the potential polarity of the static latent image; and the magnetic toner B contains an electrified charge inhibitor of which the polarity is the same as the potential polarity of the static latent image; and the absolute value of the surface potential of a developed image is up to 5-60V by keeping the electrified charge with the compound magnetic toner. In the invention, proper electrified charge is kept for the compound magnetic toner, so that developing performance and transferring property are achieved. A bright and high-definition image like a dichotomy-series toner can be obtained, and the developing method has the characteristics in use of no toner adhe
