An image forming apparatus includes a first substrate, a potential-regulated conductive element, a second substrate having an electrode and an anode electrode connected to the electrode via a resistor, and a spacer which abuts on the conductive element, electrode and anode electrode to regulate a distance between the first and second substrates. The spacer includes a base material. A first resistor film covers a side face of the base material and is electrically connected to the conductive element, electrode and anode electrode. A second resistor film covers a portion of the spacer facing the resistor, and is electrically connected to the electrode and anode electrode. A sheet resistance value of the second resistor film is less than a sheet resistance value of the first resistor film. A resistance value of the second resistor film between the electrode and anode electrode is greater than a resistance value of the resistor.

An electron apparatus includes a rear substrate having an electron-emitting device, a front substrate irradiated with electrons, and a support member for maintaining the interval between these substrates. The distribution of the electric field is controlled, and a force acting in the direction away from the support member is applied to emitted electrons to prevent the electrons from striking the support member. At this time, the electrons are accelerated toward the front substrate. Since the degree of deflection by a deflection force on the rear substrate side is larger than the degree of deflection by a deflection force on the front substrate side, the deflection force on the rear substrate side is relatively weakened.

The present invention relates to a radiation generating apparatus which includes an envelope provided with a first window through which radiation is transmitted, a radiation tube housed in the envelope and provided with a second window through which the radiation is transmitted, the second window being located at a position opposite the first window, and an insulating fluid adapted to fill the space between the inner wall of the envelope and the radiation tube. Plural plates are arranged side by side between the first window including its periphery and the second window including its periphery, and overlapping one another with gaps between them. The gaps are formed among the plates, and thereby the withstanding voltage between the first window and second window is made larger.

Provided is an X-ray generator comprising an X-ray tube including a cylindrical body; an electron source in the body; a target at an end of the X-ray tube facing the electron source, the target generating X-rays by irradiation with electrons; a container in which the X-ray tube is arranged; insulating liquid filled between the X-ray tube and the container; and a holding member holding the body of the X-ray tube in the container, with a channel for the insulating liquid around the X-ray tube. The distance between the holding member and the end face at the end of the body in the direction in which the electron source and the target face is twice or more as large as the minimum width of the channel that is in contact with the outer surface of the X-ray tube at the end face side with respect to the holding member. This allows heat in the target to be quickly radiated, thus allowing X-rays to be generated stably for a long time.
