Abstract

An image forming apparatus capable of preventing simultaneous delivery of two sheets of paper when they are supplied from a paper supply device, thereby improving operational reliability of the paper supply device. The image forming apparatus includes a body incorporating a printing device, a first paper supply unit, in which first paper is loaded, a second paper supply unit, on which second paper is disposed, at least one feed roller to deliver the second paper disposed on the second paper supply unit, a pickup roller to pick up the first paper from the first paper supply unit, and a pickup pad, which is located at a first position to contact the pickup roller when the pickup roller picks up the first paper from the first paper supply unit, and which is located at a second position spaced apart from the pickup roller when the second paper disposed on the second paper supply unit is delivered by the feed roller.
