摘要： A main vector: m^=(mx, my) and a sub-vector: s^=(sx, sy) determining cyclic structure of a basic matrix are defined, and a positional vector for a pixel configuring the basic matrix Pi^=(Pix, Piy) is defined, where the suffix i denotes an i-th pixel configuring the basic matrix. Then, the pixels configuring the basic matrix are arranged in such a manner as to satisfy the cyclic structure, and transformation of Pi^→Pi^+km^+ls^ is carried out where k and l are arbitrary integers, and may be negative values. Then a new shape of the basic matrix is obtained with Pi^+km^+ls^ as a new pixel positional vector Pi^.

摘要： An image forming apparatus is disclosed, including a fixing device and a sheet storing member. The fixing device performs both tentative fixing and regular fixing. In at least one embodiment, the fixing device performs tentative fixing for tentatively fixing a toner image on a recording sheet. Further, the fixing device performs regular fixing for further fixing the tentatively fixed toner image by contacting a gloss sheet onto the tentatively fixed toner image on the recording sheet. The sheet storing member temporarily stores the recording sheet bearing the tentatively fixed toner image before the recording sheet is sent to the fixing device for the further fixing.
