Abstract: <P>PROBLEM TO BE SOLVED: To provide a toner or an image forming apparatus having such transfer performance without causing fogging problem and without deteriorating fine dot reproducibility, having such cleaning performance as to achieve easy cleaning, and giving a high-grade image with little surface stain by a narrowed charge amount distribution.  <P>SOLUTION: The toner consists essentially of a resin and a colorant, has a form having such a rolling property as to relatively easily roll in one direction, and has a volume average particle diameter of 3-8 μm, and a material which protects a toner surface is anchored on the toner surface. The image forming apparatus uses the toner. In development, a high-grade toner image free of diffusion between white background regions or letter regions and having high thin dot reproducibility is formed. In transfer, transfer efficiency is high and the fogging due to transfer can be suppressed. In blade cleaning, cleanability comparable to that of an amorphous toner can be ensured.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
