Abstract

Provided is an image forming apparatus comprising a seal member (21) having a sliding contact layer (24) formed on an elastic support layer (22) and electrostatically filled with longer pile yarns (27a) and shorter pile yarns (27b) of different lengths. The seal member (21) is so arranged in the image forming apparatus that the sliding contact layer (24) may contact the circumference of a photosensitive drum (11) thereby to seal the leakage of a toner from the end portion of the photosensitive drum (11).
