ABSTRACT:
An apparatus unit includes a detachably mounted unit having a developing sleeve, a toner and a toner applicator, all of which are enclosed by an outer casing. The toner has a shape factor SF-1 of 100-150 and is formed of 100 parts binder, 1-20 parts of a non-magnetic color and 5-40 parts wax and has a specific storage modulus ratio (a) at 60.degree. C. and 80.degree. C. and (b) at 155.degree. C. and 190.degree. C., of at least 80 for (a) and of 0.95-5 for (b). Toner images are visualized by forming an electrostatic image, developing the electrostatic image with the toner, transferring the toner image to a transfer material and fixing the toner image by heat and pressure.
