摘要： An image forming apparatus is provided, which controls an appropriate developer amount for a desired image so that an image defect such as an unclear font or a white area is prevented, resulting in a stable image formation for a long term. A developer regulating member has a resistance value varying depending on a voltage to be applied. A control device changes over the voltage to be applied to the developer regulating member during the image formation according to image information and changes a potential difference between the developer carrying member and the developer regulating member.

摘要： A color printer has multiple developing-agent-containing cartridges each having storage units, and a cartridge holding unit for rotatably holding the developing-agent-containing cartridges. With one of the multiple developing-agent-containing cartridges positioned at an image formation position, a latent image on an image carrying member is developed by the developing agent contained in the developing-agent-containing cartridge. An access position where the storage units of the developing-agent-containing cartridges are accessed is a position other than the image formation position. This provides an image formation device and a control method thereof whereby storage units provided to developing-agent-containing cartridges can be accessed in a precise manner.
