Abstract: A developing device includes a storage portion, a developer carrying member, a stirring portion, a layer thickness restricting portion, and a guide portion. The guide portion is disposed between the stirring portion and the layer thickness restricting portion. The stirring portion faces the developer carrying member with a first gap between them. The layer thickness restricting portion faces the developer carrying member with a second gap between them. The guide portion includes a first guide surface and a second guide surface. On the first guide surface, convex portions or concave portions are formed. The first guide surface faces the stirring portion with, between them, a third gap that is a passage through which the developer passes toward the first gap. The second guide surface faces the developer carrying member with, between them, a fourth gap that is a passage through which the developer passes toward the second gap.

Abstract: An image forming apparatus includes an image carrier, a developing device, a bias applying unit, a leak detecting unit, a bias controller and a leak detection controller. The developing device includes a magnetic roller and a developer layer. The bias applying unit applies development biases to the magnetic roller and the developing roller. The leak detecting unit detects a leak generated between the image carrier and the developing roller or a leak generated between the developing roller and the magnetic roller. The leak detection controller performs a leak detecting operation for detecting the value of an inter-peak voltage of the alternating current voltage of the development bias applied to the developing roller, at which the leak is generated, while changing the inter-peak voltage at a time different from that during the developing operation.

Abstract: In an image forming apparatus, a case containing a developer includes a first storage storing developer information indicating a composition of the developer. A developing part receives the developer from the developer-containing case. An acquiring part acquires the developer information in the first storage, when the developer-containing case is installed to an installed part. A decision part decides whether or not a composition of the developer in existing developer information in a second storage is different from another composition of the developer in newly acquired developer information. An electric charge amount measuring part measures an electric charge amount of the developer in the developing part. A developer replacement controlling part controls discharge and replenishment of the developer in the developing part on the basis of the measured electric charge amount, when the decision part decides that both compositions are different.

Abstract: A touch screen displays a plurality of images corresponding to a plurality of colors represented by color information stored in a color information storage unit. A selection part indicating whether the image is in a selected state or an unselected state is associated with each image displayed on the touch screen. An intermediate color calculating unit calculates color information representing an intermediate color of two colors indicated by images respectively corresponding to two selection parts in the selected state. An intermediate color adding unit displays on the touch screen an image corresponding to the intermediate color, based on color information of the intermediate color calculated by the intermediate color calculating unit, and a selection part corresponding to the image. An output unit outputs the color information of the intermediate color corresponding to the selection part if the selection part corresponding to the intermediate color is selected.
