Summary: | PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing the generation of transfer memory.SOLUTION: An image forming apparatus 1 includes photoreceptor drums 41y to 41k, destaticization devices 45y to 45k, transfer rollers 54y to 54k, a transfer power supply device, and energizing members 542y to 542k. The photoreceptor drums 41y to 41k are arranged along the travel direction of a transfer target body 51. The destaticization devices 45y to 45k destaticize the photoreceptor drums 41y to 41k adjacent to the upstream side in the travel direction of the transfer target body 51. Further, the destaticization devices 45y to 45m destaticize the photoreceptor drums 41c to 41k adjacent to the downstream side. The transfer power supply device applies a potential to each of the transfer rollers 54y to 54k. The energizing members 542y to 542k energize the transfer rollers 54y to 54k toward the photoreceptor drums 41y to 41k. A pressing force with respect to the photoreceptor drum 41k is set larger than a pressing force with respect to the photoreceptor drum 41y.SELECTED DRAWING: Figure 2
【課題】転写メモリーの発生を抑制できる画像形成装置を提供する。【解決手段】画像形成装置1は、感光体ドラム41y〜41k、除電装置45y〜45k、転写ローラー54y〜54k、転写電源装置及び付勢部材542y〜542kを備える。感光体ドラム41y〜41kは、被転写体51の進行方向に沿って配置される。除電装置45y〜45kは、被転写体51の進行方向上流側に隣接する感光体ドラム41y〜41kを除電する。更に除電装置45y〜45mは、下流側に隣接する感光体ドラム41c〜41kを除電する。転写電源装置は、転写ローラー54y〜54kにそれぞれ電位を付与する。付勢部材542y〜542kは、転写ローラー54y〜54kを感光体ドラム41y〜41kに向けて付勢する。感光体ドラム41kに対する押圧力は、感光体ドラム41yに対する押圧力よりも大きく設定される。【選択図】図2 |
