<p>The invention is to provide a flat panel image forming apparatus capable of suppressing a fluctuation in an incident position of an electron beam resulting from a front-rear temperature difference generated in a panel, thereby capable of high-quality display not affected by such temperature difference.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">In an image forming apparatus in which a face plate (1) and a rear plate (2) are supported by a spacer (3), a heat resistance division ratio in a heat conduction path from the face plate (1) to the rear plate (2) is suppressed to 0.5 or less, to reduce an electrical resistance distribution on the spacer surface, resulting from a temperature distribution in a direction of height of the spacer (3) thereby suppressing a fluctuation in the incident position of the electron beam from an electron emitting device to an anode.
