Abstract
An image forming apparatus with an image forming area selection function has an original table on which a light-transmitting original is set such that an original image surface selectively faces upward or downward, a light-transparent section for emitting light transmitting through the original set such that the original image surface faces upward on the original table while the light is shifted with respect to the original, an erasure area specifying section for specifying an unnecessary portion of the original image surface to specify an erasure area while the light from the light-transmitting section is being shifted, an erasure area storage section for storing position data of the erasure area specified by the erasure area specifying section, an original scanning section, having an optical system moved along the original table, for scanning the original placed such that the original image surface faces downward, an image forming section for focusing light emitted from the original scanning section and reflected by the original and for developing an image on an image forming medium to form an image, an image erasing section for selectively erasing an image to be formed by the image forming section, and a control section for reading out the position data corresponding to the erasure area from the erasure area storage section at any time during the operation of the image forming section.
