一体に連結して成る。FIG. 1 is an explanatory view of the usage of the developer seal for transportation of the present embodiment (FIG. 1A is a side view showing a state in which the seal is attached,
FIG. 1 (B) is a side view showing the procedure for pulling out the seal). In the figure, reference numeral 21 is a developer seal for transportation. The same reference numerals are used for the same members as the conventional ones. A developer developer seal (hereinafter abbreviated as developer seal) 21 for transportation includes a flexible protective film 22 of a polyethylene film having a thickness of 50 μm, which is elastic and flexible, at one end of a flexible film of a conventional developer seal. Consists of connecting.

時における現像剤こぼれ落ちを防ぐことができる。When the developer seal 21 is used for transporting the apparatus, as shown in FIG. 1A, the flexible film 7 is passed between the photoconductor 1 and the developing roller 5, and the closing portion 8 is left as a gap. The protective sheet 22 is positioned outside the case 4 while being pushed into the gap 11 to close the gap 11. In this example, the case where the protective sheet 22 is passed over the charger 12 on the lower side of the photoconductor 1 is shown, but if there is a gap between the charger 12 and the case 4, the protective sheet 22 hangs down in the gap. Is also good. In this state, since the blocking portion 8 closes the gap, it is possible to prevent developer spillage during transportation of the apparatus.
