An image forming device. A direct voltage power supply is independently provided for each charging device for each color, and an alternating voltage power supply is commonly provided to the charging device for each color. A current detecting section detects current which flows between each image carrying body and each charging device. A control device judges that the image carrying body is damaged when a detected current value is not less than a preliminarily set specified value when a direct voltage is sequentially independently applied to the charging device for each color when leakage of charging voltage is generated.

A belt member is seamed to form an endless belt which is stretched by a plurality of roller members and circulated in a first direction. The belt member is provided with an electrode portion at a first end portion thereof in a second direction perpendicular to the first direction. A cleaning member is abutted against the belt member. A seam of the belt member extends obliquely relative to the first direction such that an end of the seam confronting the electrode portion is situated in an upstream side of the first direction.

The object of the invention is to provide an image carrier which is capable of securely preventing the leakage of charge in lateral direction so as to stably conduct the application or removal of charge and which can be easily manufactured. An image carrier comprises a dielectric layer, wherein charge is transferred between the dielectric layer and a charge-transfer controlling means so as to apply charge to or remove charge from the dielectric layer, wherein the dielectric layer is formed in such a structure that a large number of conductive portions are formed to be separately dispersed in its outer surface. Charge is transferred between the conductive portions and the charge-transfer controlling means so as to apply charge to or remove charge from the conductive portions.

摘要:
Provided is a printing apparatus for printing an image on a medium, which is transported in a transport direction, by forming dots by ejecting ink from a plurality of nozzles while moving the nozzles in an intersecting direction that intersects the transport direction. The printing apparatus has a first printing mode for printing a mirror image of a predetermined image as the image on the medium and a second printing mode for printing a positive image of a predetermined image as the image on the medium, the medium being a transparent medium. The first printing mode is different from the second printing mode in at least one of a transportation operation of transporting the medium and a dot-forming operation of forming the dots by ejecting ink while moving the nozzles.
