ABSTRACT:
An image forming apparatus includes a paper delivery detecting switch provided near the paper delivery opening, a paper presence detecting structure to detect the presence of the paper on the receiving tray, a counter circuit and a comparator. The counter circuit counts up the number of delivered paper on the receiving tray in response to a delivered paper signal from the paper delivery detecting switch and a paper presence signal from the paper presence detecting structure. The comparator compares the value of number of delivered paper counted up by the counter circuit and a delivery quantity limit value preset in the apparatus main body, and halts the image forming operation when the two values coincide.
