FERRITE PARTICLES, ELECTROPHOTOGRAPHIC DEVELOPER CARRIER CORE MATERIAL, ELECTROPHOTOGRAPHIC DEVELOPER CARRIER, AND ELECTROPHOTOGRAPHIC DEVELOPER
[Problems] The present invention addresses the problem of providing: high-strength ferrite particles that can suppress the occurrence of carrier scattering even in high temperature, high humidity environments; an electrophotographic developer carrier core material; an electrophotographic developer carrier; and an electrophotographic developer.[Solution] In order to resolve the aforementioned problem, provided are ferrite particles comprising a crystal phase component comprising perovskite crystals represented by the compositional formula RZrO3 (where R is an alkaline earth metal element), the ferrite particles having an apparent density within a prescribed range. The ferrite particles are used as an electrophotographic developer carrier core material. Using the same, an electrophotographic developer carrier and an electrophotographic developer are obtained.
