摘要：
A wet electrophotographic image forming machine that informs a user of a timing for replacing development cartridges. The image forming machine comprises a control section for sensing the condition of the developer stored in one or more developer housings on the basis of a measured electric current flowing between one or more developer feeding members and one or more developer application members via the developer provided therebetween, and a display section for externally displaying the developer condition according to a signal from the control section. The control section evaluates the magnitude of the electric current and provides a signal to the control section for display if there is a developer amount or concentration deficiency.
