Particles, toner, developer, image forming apparatus, and image forming method

Abstract

Particles comprising base particles and an external additive are provided. The base particles contain a resin, and the resin comprises polyester as a main component. The polyester comprises at least one of polyethylene terephthalate and polybutylene terephthalate. The external additive is coated with a hydroxide of a metal. R1≤R2 and R3≤R4 are satisfied, where R1 [log Ωcm] is a resistance value of the external additive and R2 [log Ωcm] is a resistance value of the base particles, at 25° C. and a humidity of 50%, and R3 [log Ωcm] is a resistance value of the external additive and R4 [log Ωcm] is a resistance value of the base particles, at 40° C. and a humidity of 70%.
