Abstract
An object of the invention is to cause a transfer device to make more stable contact with a belt, thus yielding preferable transfer performance. In an image-forming apparatus 100 in which the transfer device has a sheet member 52, the sheet member 52 includes a conductive sheet 52b, and an electrical connection path section (power source connecting section 55) for supplying voltage to the conductive sheet 52b from the primary transfer power source 16, and the power source connecting section 55 is arranged outside an image formation enabling region Lp where a toner image can be formed on a photosensitive drum 1, in a perpendicular direction to the direction of movement of the intermediate transfer belt 7.
Claims13
An image-forming apparatus, comprising:
- an image bearing member which bears a toner image;
- a movable belt;
- and
- a transfer device arranged to face the image bearing member via the belt, the transfer device being provided with a sheet member, wherein
- the sheet member has a conductive section and an electrical connection path section for supplying voltage from a power source to the conductive section, and
- the connection path section is arranged outside an image formation enabling range where a toner image can be formed on the image bearing member, in a direction perpendicular to a direction of movement of the belt.
An image-forming apparatus, comprising:
- an image bearing member which bears a toner image;
- a movable belt;
- and
- a transfer device arranged to face the image bearing member via the belt, the transfer device including a conductive brush member, a planar supporting member which supports the brush member, and an electrical connection path section for supplying voltage to the brush member from a power source, wherein
- the connection path section is arranged outside an image formation enabling range where a toner image can be formed on the image bearing member, in a direction perpendicular to a direction of movement of the belt.
