IMAGE FORMING APPARATUS

摘要

An image forming apparatus containing an electrophotographic photoreceptor and a toner for developing an electrostatic charge image, where the electrophotographic photoreceptor has an undercoat layer containing metal oxide particles; the toner for developing an electrostatic charge image is a toner for developing an electrostatic charge image containing toner matrix particles formed in an aqueous medium; the toner has a volume median diameter (Dv50) of from 4.0μm to 7.0μm; and the relationship between the volume median diameter (Dv50) and the percentage in number (Dns) of toner particles having a particle diameter of from 2.00μm to 3.56μm satisfies the following formula (1): Dns≰0.233EXP(17.3/Dv50)  (1) where Dv50 is the volume median diameter (μm) of the toner, and Dns is the percentage in number of toner particles having a particle diameter of from 2.00μm to 3.56μm.
