<p>PURPOSE: To provide the toner for an electrophotography furnished with the cleaning property of an irregular form toner as well as the transferring property of a spherical toner, by mixing the irregular shape toner and the spherical toner. CONSTITUTION: In the toner for an electrophotography transported by the toner carrier 5 for making the electrostatic latent image on the electrostatic latent image carrier 1, the irregular form toner and the spherical toner are mixed up. Then the average grain size of the irregular form toner is made large than the average grain size of the spherical toner. Moreover, the mixing ratio by weight of the spherical toner is made <=20%. Furthermore, as for the spherical toner, when assuming the area of the circle whose diameter is the absolute maximum length of the toner particle as Sc and the substantial projection area of the toner particle as Sr, the value of Sc/Sr is made to be in the range of 1.0 to 1.3. In this way, the toner for the electrophotography provided with the cleaning property of the irregular form toner as well as the transferring property of the spherical toner can be relatively easily realized.</p> |
