Abstract:
1. An image-forming device comprising: a main casing; a photosensitive member having a surface; a charging unit that charges the surface of the photosensitive member; an exposing unit that forms an electrostatic latent image on the surface of the photosensitive member after the photosensitive member has been charged by the charging unit; a developing unit that develops the latent image formed on the surface of the photosensitive member into a visible image using a developer; a transferring unit that transfers the visible image developed by the developer onto a recording medium; an inspection member receiving section in which an inspection member is detachably mountable; a driving unit that selectively drives the charging unit, the developing unit, and the transferring unit as a target unit to be driven; a switching unit that switches an operating mode between a normal mode for forming images on the recording medium and a self-diagnostic mode for performing a self-diagnosis, the switching unit switching from the normal mode to the self-diagnostic mode when the inspection member is mounted in the inspection member receiving section; a drive commanding unit that outputs a self-diagnostic drive command to the driving unit to command the driving unit to drive the target unit when the switching unit has switched to the self-diagnostic mode; and a diagnosing unit that determines whether an operating state of the driving unit is normal based on drive commands received from the drive commanding unit, wherein the inspection member receiving section is further configured to couple the inspection member to the driving unit when the inspection member is mounted in the inspection member receiving section.
