Abstract: An image forming apparatus includes a sheet feed unit having a sheet feed port, an image forming unit, a sheet position detector, a mode selector, and a memory unit. The sheet feed unit feeds a recording sheet. The image forming unit forms an image on the recording sheet. The sheet position detector detects a sheet edge of the recording sheet. The mode selector selects at least one of the position correction mode and non-correction mode for the sheet feed port. An image forming position on the recording sheet is corrected using position information detected by the sheet position detector when the position correction mode is selected, and the image forming position on the recording sheet is not corrected when the non-correction mode is selected. A memory unit may store a plurality of values of light intensity and threshold value corresponding to different types of recording sheets.

Abstract: An image forming apparatus includes an information obtainer, a memory, a candidate determining unit, and an image forming device. The information obtainer obtains feature information from the target recording medium. The memory stores at least one set of recording medium information regarding the target recording medium associated with the feature information and at least one set of image forming condition information corresponding to the recording medium information. The recording medium information is identification information. The candidate determining unit determines a candidate recording medium information from the recording medium information stored in the memory based on the feature information of the target recording medium obtained by the information obtainer. The image forming device forms an image on the target recording medium based on the image forming condition information in the memory according to the candidate recording medium information determined by the candidate determining unit.
