The present invention provides a toner for a electrostatic latent image development and an image forming method which could print an image having the high quality for a long time period by forming a thin toner layer having a uniform thickness on a developing sleeve and, at the same time, by maintaining a surface of a photoconductor in the clean conditions irrespective of a change brought about by a lapse of time or an environmental change. In a toner for electrostatic latent image development which is used for an image forming apparatus comprising an electrophotographic photoconductor and a developing sleeve which is arranged close to the electrophotographic photoconductor, the toner is externally added with at least silica and titanium oxide to toner particles containing a magnetic powder, wherein assuming Si strength of the toner as ISi, Ti strength of the toner as ITi and Fe strength of the toner as IFe when these strengths are measured by using a fluorescent X-ray analyzing device, the following relationships (1) and (2) are satisfied. 9.0×10−3≦ISi/IFe≦1.0×10−2  (1) 6.0×10−3≦ITi/IFe≦8.0×10−3  (2)
