PROBLEM TO BE SOLVED: To provide a method and apparatus for measuring electrostatic latent images, which adjusts the displayed magnification so as not to generate inconsistencies between the displayed magnification and actual magnification, and to provide an image forming apparatus, a latent image carrier, a program for measuring an electrostatic latent image, and a computer-readable recording medium. SOLUTION: The apparatus for measuring the electrostatic latent image mainly includes a charged particle gun 11; apertures 12 and 12A; a condenser lens 13; a beam blanker 14; a beam deflection means 15; an objective lens 16; a charged particle beam drive section 31; an exhaust means 33; a computer 40; a semiconductor laser 17 being the first light source; a collimating lens 18; an aperture 19; lenses 21, 22, and 23 that configure "imaging lens"; a semiconductor laser drive section 32; a device for capturing the charged-particles 24; a charged particle detecting section 25; a signal processing section 26; a sample-hold pedestal 28; a sample SP; a light-emitting device 29 for removing electricity (second light source: LED); an LED drive section 35; and a sample pedestal drive section 34, where the apparatus changes the refractive power of the objective lens 16 or the display that shows magnification according to the voltage applied.
