An electrophotographic apparatus includes a movable electrophotographic photosensitive member, a charger for uniformly charging the photosensitive member, a first device for forming a first electrostatic latent image by exposing the photosensitive member charged by the charger to negative image light corresponding to first image information, a first developing device for developing through a reversal development the first electrostatic latent image into a first visualized image, a second device for exposing the photosensitive member having the first visualized image to positive image light corresponding to second image information to form a second electrostatic latent image, a second developing device for developing through a regular development the second electrostatic latent image into a second visualized image, wherein a potential level in an area of the photosensitive member exposed to the light by the second device is between a potential level in an area of the photosensitive member exposed to the light by the first electrostatic latent image forming device and a potential level in a non-exposed area of the photosensitive member, and is between a potential level of the first visualized image and the level of non-exposed area.
