Abstract: In an image forming apparatus, a developer containing 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 the compositions are different.

Abstract translation: 在图像形成装置中，包含显影剂的显影剂容纳盒包括第一存储器，存储指示显影剂组成的显影剂信息。 显影部件从显影剂容纳盒接收显影剂。 当将显影剂容纳盒安装到安装的部件上时，获取部件获取第一存储器中的开发者信息。 决定部分决定第二存储器中的现有开发者信息中的开发者的构成是否与新获取的开发者信息中的开发者的另一组成不同。 电荷量测量部分测量显影部分中的显影剂的电荷量。 当决定部分确定两个组成不同时，显影剂更换控制部分基于测量的电荷量控制显影部分中的显影剂的放电和补充。
