光体上に形成された静電潜像を、現像剤のキヤリ
アとともに搬送されるトナーにより現像する現像
装置であつて、 トナーホツパーから補給されるトナーを、その
回転により現像剤と撹拌する撹拌ローラと、 該撹拌ローラに、その回転速度が変化するよう
に動力を伝達する伝動機構と、 を具備する現像装置。[Scope of Claim for Utility Model Registration] A developing device in which toner is sequentially replenished from a toner hopper and develops an electrostatic latent image formed on a photoreceptor with toner conveyed together with a carrier of developer, which is supplied from a toner hopper. What is claimed is: 1. A developing device comprising: an agitating roller that agitates toner and a developer through its rotation; and a transmission mechanism that transmits power to the agitating roller so that its rotational speed changes.
