Abstract

To provide a mechanism for appropriately controlling the timing to replace an intermediate transfer belt.SOLUTION: An image forming apparatus of the present invention comprises: an intermediate transfer unit that has an intermediate transfer belt and a transfer residual toner storage container; life detection means that detects the state of the life of the intermediate transfer belt; fullness detection means that detects the fullness of the transfer residual toner storage container; and control means that controls the operation of the image forming apparatus on the basis of the state of detection performed by at least one of the life detection means and the fullness detection means.SELECTED DRAWING: Figure 5
