The object of the invention is to provide a toner enabling excellent transferring properties, cleanability, and fixability and forming a high-precision image without substantially degraded image quality even after printed on a number of sheets of paper. The invention also provides the toner-production method, an image forming apparatus, an image forming method, and a process cartridge. To this end, the present invention provides a toner which comprises toner-base particles containing a binder resin and a filler, and inorganic fine particles, in which the filler is included in a filler-layer in the vicinity of surfaces of the toner-base particles, the number average particle diameter of the primary particles of the inorganic fine particles is 90 nm to 300 nm, and the average circularity of the toner is 0.95.
