An image forming apparatus includes a receiving unit, an image forming unit, a determining unit, an analyzing unit and a control unit. The receiving unit receives image data. The image forming unit performs a predetermined image forming process based on the image data received by the receiving unit. The determining unit determines as to whether or not the image data contains a barcode pattern. When the determining unit determines that the image data contains the barcode pattern, the analyzing unit analyzes as to whether a drawing direction of the barcode pattern is a vertical direction or a horizontal direction. The control unit that controls, based on an analyzing result of the analyzing unit, the predetermined image forming process being performed for the barcode pattern by the image forming unit.

A ROM stores density conversion tables appropriate for a present apparatus to execute recording and standard density conversion tables. As a command is entered on a control panel, a CPU sets the optimum density conversion table in a RAM and again converts image data of 256 levels of gradation for a density adjustment. Resultant image data undergoes false halftone processing in an error diffusion circuit and is transmitted to the present apparatus or a destination recorder. When the record characteristic of the destination recorder is unknown, the standard density conversion table is used, so that no large difference occurs for recording.

An image signal sent from an image sensor is input to the inverting terminal of a differential amplifier. An A/D converter converts an output of the differential amplifier to digital output data. A comparison circuit compares the digital output data with a reference value in a dummy bit period to produce a comparison result, for instance, a difference between the digital output data and the reference value. Based on the comparison result, a correction value setting circuit modifies a correction value so that a DC offset becomes closer to the reference value. For example, the correction value setting circuit adds the difference obtained by the comparison circuit to the correction value. A D/A converter converts the modified correction data to an analog voltage, which is input to the noninverting terminal of the differential amplifier.
