Title:
IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2022102967
Kind Code:
A
Abstract:
To increase an ability to move a foreign substance to an upstream-side image carrier to reduce the amount of foreign substance moving to a downstream-side image carrier, thereby preventing an image defect caused by the foreign substance in association with the extension of life of units including the image carrier and a developing device.SOLUTION: An image forming apparatus 1 has a first image forming section PY, a second image forming section PM, a belt 12, an electrification voltage application section E1, and a transfer voltage application section E3. In the direction of movement of a recording material S, the first image forming section PY is arranged upstream of the second image forming section PM. In an image forming operation, the potential difference between a first transfer voltage and a potential at which an image formed on a first image carrier 4Y in a first transfer section NY is not formed, is larger than the potential difference between a second transfer voltage and a potential at which an image formed on a second image carrier 4M in a second transfer section NM is not formed.SELECTED DRAWING: Figure 5
