11! In many cases, the toner collection box 15a, which occupies the bottom of the cleaning device 15, is arranged very close to each other, and as a result of the above-mentioned floating of the recording paper, its upper surface is placed in the toner collection box 15. There were many cases where the toner image was damaged by scratches on the bottom surface of the paper.
本発明は、前述した如き片側基準の搬送におけの複写機

ことは勿π泊であて、。That is, by providing the guide member 32, the released side end surface Pa of the recording paper is aligned with the slope plane, 3] a
When attempting to float during transportation, the guide is always downwardly restricted, so there is a very small possibility that the guide will deform into a wave shape and float. As the restraining force of the member 32 becomes stronger, it is unlikely that the toner image will float further and avoid scraping the bottom surface of the toner collection box 25m or the lower surface of other structures. As an example, in addition to the guard member 32 as shown in FIG.
For example, it may be a ring member that rotates in the direction of recording 1, or one or more guide members may be provided.
Of course, I will stay overnight.
