Abstract
A toner for developing an electrostatic latent image, wherein in regard to the molecular weight by GPC of the THF dissolved components of the toner, the ratio of at least 5×10 in the integral molecular weight distribution is not higher than 1% by weight, the ratio of not higher than 3×10 is not higher than 30% by weight, and the ratio {W(5×10 )/W(1×10 )} of the ratio {W(5×10 )} of not higher than 5×10 to the ratio {W(1×10 )} of at least 1×10 is from 15 to 50. Also, the molecular weight by GPC of the THF dissolved components of the toner is distributed in the range of not larger than 1×10 , the value of the differential molecular weight distribution of the molecular weight of 5×10 is not larger than 0.55%, and the value of the differential molecular weight distribution of the molecular weight of 1×10 is not larger than 0.15%.
