摘要： A developing device, includes a developer agitating member, an upstream side developing miler, and a downstream side developing roller; wherein the toner in the developer handed over from the upstream side developing roller to the downstream side developing roller has a volume average particle size larger than a volume average particle size of the toner in the developer conveyed by the upstream side developing roller to the facing position between the upstream side developing roller and the photoreceptor.
