<p>An electrophotography apparatus for performing exposure and recording of information onto a charged photosensitive body using a line head consisting of an array of a large number of EL elements, developing the information-recorded photosensitive body, and transferring a developed image onto a recording medium, includes a current detection unit (61 - 64) for detecting peak values of AC currents flowing through electrodes of the EL elements when the EL elements emit light, and a discriminator (75 - 68) for discriminating based on current detection outputs from the current detection means whether or not the EL elements are defective. In this arrangement, the EL elements of the line head are caused to emit light, peak values of AC currents flowing through the electrodes of the EL elements are detected, and whether or not the EL elements are defective is discriminated based on the detected current peak values. <IMAGE></p> |
