| 发明名称 | Image forming apparatus employing cleanerless system | ||
| 摘要 | An image forming apparatus includes a developing roller and a photosensitive drum configured to rotate about a first axis, and has a peripheral surface. The developing roller is configured to contact the photosensitive drum and is configured to supply developer to the photosensitive drum by rotating about a second axis positioned lower than the first axis in a vertical direction to form a visible image on the peripheral surface. Extraneous matter on the peripheral surface is recovered only by the developing roller. | ||

| 主权项 | 1. An image forming apparatus comprising: a photosensitive drum configured to rotate about a first axis and having a peripheral surface; a developing roller configured to contact the photosensitive drum and configured to supply developer to the photosensitive drum by rotating about a second axis positioned lower than the first axis in a vertical direction to form a visible image on the peripheral surface, extraneous matter on the peripheral surface being recovered only by the developing roller; and a film member overlapping the first axis when projected in the vertical direction and having a portion contacting a circumferential surface of the developing roller. | ||
