    摘要： An image-forming apparatus is comprised of substrate, an electron-emitting device which is provided on the substrate, has an electron-emitting region between electrodes, and emits electrons on application of voltage between the electrodes, and an image-forming member which forms an image on irradiation of an electron beam, wherein the diameter S₁ of the electron beam on the image-forming member in direction of application of the voltage between the electrodes is given by Equation (I):

    S₁ = K₁·2d(V f /V a ) 1/2    (I)

    where K₁ is a constant and 0.8 ≦ K₁ ≦ 1.0, d is a distance between the substrate and the image-forming member, V f is a voltage applied between the electrodes, and V a is a voltage applied to the image-forming member.
    A method for designing a diameter of an electron beam at an image-forming member face of the image-forming apparatus is comprised of that the diameter S₁ of the electron beam at the image-forming member face in direction of application of the voltage between the electrodes is designed so as to satisfy the equation (I).
