ABSTRACT:
A toner is used in an image-forming apparatus that incorporates a toner-collecting member. The toner-collecting member collects residual toner on a surface of an image-bearing body. 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 μm. 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. The irregularly shaped particle is charged opposite in polarity to the spherical toner. The irregularly has a roundness of 0.85 or less.
