Abstract: An image forming apparatus includes: an image reading device that optically reads a document to obtain image data; a character recognizer that recognizes a character pattern included in the image data as a character; a character estimator that, for the character pattern that the character recognizer failed to recognize, from characters, which precede and follow the character pattern and have been recognized by the character recognizer, estimates, in accordance with a grammar rule, a character that the character pattern indicates; and an image data reconfigurer that arranges each character recognized by the character recognizer and each character estimated by the character estimator in an order same as an arrangement order of each character pattern included in the image data to generate reconfigured image data.

Abstract: An image forming apparatus includes an original setting part, an original reading device, an opening/closing member, a locking mechanism, a notifying mechanism, an original detecting part, a user detecting part and a controlling part. The opening/closing member is switchable between an opening posture and a closing posture. The locking mechanism holds the opening/closing member in the closing posture. The notifying mechanism notifies a user that the original is left behind on the original setting part. The controlling part operates the locking mechanism and the notifying mechanism on condition that the original detecting part detects the original and the user detecting part does not detect the user in a state where the original reading device has finished reading the original. The controlling part stops operation of the locking mechanism on condition that authentication of a specific user succeeds in a state where the locking mechanism is operated.
