摘要： A foamed elastic member according to the invention comprises an elastic member made of polyurethane foam molded by an in-mold foaming process, and has properly determined physical properties of its surface and/or properly determined shape and arrangement of foam cells opened on the surface. The foamed elastic member is suitably used for a toner feed roller in a developing device for electrically charging toner from a toner storage portion, feeding the toner onto the surface of a photosensitive member and forming a toner image corresponding to an electrostatic latent image on the surface of the photosensitive member. In this case, it exhibits an excellent toner scraping and toner feeding performance, to form an image free from such defect as irregularity in pitch and density, or free from reduction in density.
