    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: An image forming apparatus includes an image carrier, a developing part, a storing part and an adjusting part. The image carrier includes a surface. An electrostatic latent image formed on the surface is developed by a toner, and then, a toner image is formed on the surface. The developing part contains the toner supplied from a toner cartridge and supplies the toner to the image carrier. The storing part stores information relating to a replacement rate when a first toner in the developing part is replaced by a second toner, in a case where kinds of the first toner contained in the developing part and the second toner being supplied from the toner cartridge are different. The adjusting part adjusts density of the toner image on the basis of the replacement rate when a toner cartridge containing the first toner is replaced by another toner cartridge containing the second toner.

    Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member, a temperature sensor and a controller. A detected region whose temperature is detected by the temperature sensor is formed in the fixing belt, and an elastic layer of the detected region is provided with a hole in a part thereof in a circumferential direction. The controller judges that the fixing belt is rotating in a case where the temperature detected by the temperature sensor alternately increases and decreases in a state that the heat source is heating the fixing belt, and judges that the fixing belt is not rotating in a case where the temperature detected by the temperature sensor does not alternately increase and decrease in the state that the heat source is heating the fixing belt.
