    摘要： An image forming method and image forming apparatus based on the application thereof wherein comet-like deposits do not appear on the surface of the photoreceptor even after prolonged use of small-diameter toner, and there is no dropout or damage on the photoreceptor surface in the image forming process using an intermediate transfer member. This image forming method contains a process wherein the toner developed on an electrophotographic photoreceptor is transferred onto an intermediate transfer member, and the toner contains at least a metallic oxide and metallic soap added as external additive agents, and the protective layer contains a resin component obtained by reaction of at least a curable compound, and alumina particles.
