The present invention provides ferrite powders for bonded magnet capable of suppressing increase of SFD, while widening a particle size distribution for obtaining flowability and compressed density, and also capable of suppressing deterioration of orientation and magnetizability, and provides a process for a production magnetoplumbite-type ferrite powders containing an oxide of at least one or more kinds of transition metals selected from a group consisting of Zr, Ti, Zn, Co, Mn, and Ni, having a mean particle size of 0.20µm or more and less than 5.00 µm, being the ferrite powders for bonded magnet with the ratio of particles having particle size of 1µm or less being 20mass% or more in the magnetoplumbite-type ferrite powder size distribution obtained by a laser diffraction type particle size distribution analyzer.
