Toner, toner cartridge, and image forming apparatus

Abstract

A toner includes toner base particles and an external additive. The external additive is adhered to surfaces of the toner base particles, which contain a crystalline polyester resin and an ester wax. The proportion of an ester compound with a carbon number of C1, the content of the ester compound with a carbon number of C1 being highest among the ester compounds constituting the ester wax, is 65 mass % or more with respect to 100 mass % of the ester wax. The carbon number distribution of the ester compounds constituting the ester wax has only one maximum peak in a region where the carbon number is 43 or more. The external additive contains silica particles having a volume average primary particle diameter D50of 40 to 75 nm. The moisture content of the silica particles is less than 1.0 mass % with respect to 100 mass % of the silica particles.
