Embodiment Construction

[0055] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the following examples, although a two-component developer composed of a toner and a carrier is used, the two-component developer is simply referred to as a toner in the following description.

[0056] figure 1 This is a cross-sectional view illustrating the internal configuration of a full-color image forming apparatus (hereinafter simply referred to as a printer) according to an embodiment of the present invention.

[0057] figure 1 The illustrated printer 1 is a tandem color image forming apparatus of an electrophotographic secondary transfer method, and consists of an image forming unit 2 , a transfer belt unit 3 , a toner supply unit 4 , a paper supply unit 5 , and a belt unit. The fixing unit 6 and the conveying unit 7 for double-sided printing are constituted.

[0058] The above-mentioned image forming unit 2 is composed of four develop...

Abstract

In a new printer, a toner cartridge is mounted in the state where there is no toner in a reserve tank, and toner of the amount of filling toner D therein is supplied with the amount of full accommodation toner E for filling up the reserve tank by a toner supply mechanism. The toner of the amount of remaining surplus toner F remains in the toner cartridge. The amount of toner consumption G is measured by a dot counter during a printing execution. In the case where a toner density sensor detects a toner decreasing, the toner is supplied to a developing unit from the reserve tank. When it becomes G>F, it display-informs a user of "toner cartridge exchange is allowed". Hereby, it enables to exchange the toner cartridge without stopping operation of the main body of the image forming apparatus using a two-component developer.
