<p>An apparatus for forming an image of a document, capable of charging a photoconductor (11) by using a charging device (12) includes a unit (17) for detecting a value of a flowing current into the photoconductor (11), a unit (21) for comparing the value of the flowing current with a predetermined life time current value of the photoconductor (11), and a unit (in L1) for determining a layer thinning of the photoconductor at a time when the value of the flowing current exceeds the predetermined life time current value of the photoconductor (11) so that the layer thinning is indicated. <IMAGE></p> |
