Image forming method |
摘要 |
<p>An electrophotographic image forming method according to (I) a so-called simultaneous development and cleaning scheme or cleaner-less scheme is effectively operated by using a specific non-magnetic toner. (II) The non-magnetic toner comprises non-magnetic toner particles having a shape factor SF-1 of 120 - 160, a shape factor SF-2 of 115 - 140 and a weight-average particle size of 4 - 9 mu m. (III) The non-magnetic toner further includes inorganic fine particles (a) having a number-average primary particle size of at most 50 nm and spherical fine particles (b) having a number-average primary particle size of 50 - 1000 nm and a surface area-based sphericity psi of 0.91 - 1.00, respectively externally added to the non-magnetic toner particles. <IMAGE></p> |
