摘要： An image forming apparatus includes a primary transfer device that primarily transfers a first image from a first image bearer onto a first belt unit at a primary transfer position, a secondary transfer device that secondarily transfers the first image from the first belt unit onto a printing medium at a secondary transfer position, and a direct transfer device that directly transfers a second image from a second image bearer onto the printing medium at a direct transfer position. A second belt unit is rotatably suspended by plural second rollers and carries and conveys the printing medium through the direct transfer position and the secondary transfer position. An interval between the direct transfer position and the secondary transfer position is prescribed natural number times of a circumference of one of the plural second rollers, which fluctuates a velocity of the second belt unit.

摘要： An electrophotographic method and apparatus includes a frame having a used toner inlet, a new toner inlet and a combined toner outlet. Opposing sides of the frame are positioned at predetermined angles with respect to a horizontal line extending from a bottom of the frame. The used toner inlet is positioned in an upper portion of the frame next on one of the sides positioned at a predetermined angle, while the new toner inlet is also positioned in the upper portion of the frame, but next to the other side. The predetermined angle of the frame's side that is next to the used toner inlet is at a greater angle than the other side so as to compensate for any degradation in the flow characteristic of the used toner as a result of the recycling process. The frame is configured to interface with a new toner bottle having an opening that cooperates with the new toner inlet. Accordingly, when the new toner supply is exhausted, the new toner bottle may easily be replaced without having to remove any other components.
