The toner- collecting member (6a) collects residual toner (16a) on a surface of an image-bearing body (1). The toner includes a spherical toner having at least a binder resin, and an irregularly- shaped particles mixed with the spherical toner. The irregularly shaped particle has an average diameter in the range of 1-50 mu m. The average diameter is 14 to 10% of the diameter of a spot printed by the image-forming apparatus. The irregularly shaped particle is a toner having the same color as the spherical toner. The irregularly shaped particle is a colorless toner.
