摘要：
To provide an image forming apparatus using a toner having inorganic fine particles externally added thereto, wherein a detached ratio R1 of the inorganic fine particles from the non-transferred toner is from 0% to 20%, a detached ratio R2 of the inorganic fine particles from toner passed through the collecting unit is from 20% to 80%, and a ratio of the detached ratio R2 to the detached ratio R1, R2/R1, is 1.5 or more.
