PROBLEM TO BE SOLVED: To provide a tandem image formation device and an abnormality detection method which can specify toner image formation means where such an abnormality that toner adheres to a latent image carrier occurs under an imaging condition of a blank image while suppressing cost increase.SOLUTION: In a printer 10 being a tandem image formation device, a control part drives a plurality of process units 30 under an imaging condition corresponding to a blank image where toner is prevented from adhering onto a photoreceptor 60, executes initial agent setting control being blank image formation control for driving a primary transfer roller 130 and an intermediate transfer belt 50, and specifies the process unit 30 in which toner having a toner adhesion amount equal to or greater than a prescribed amount adheres onto the photoreceptor 60 on the basis of the time from the start of initial agent setting control to detection of the toner adhesion amount equal to or greater than the prescribed amount when a photosensor 300 detects the toner adhesion amount equal to or greater than the prescribed amount on the intermediate transfer belt 50 during execution of the initial agent setting control.SELECTED DRAWING: Figure 1 |
