Image forming system, image forming apparatus and image forming method

摘要

An image forming apparatus capable of printing at a transfer voltage and fusing temperature that are suited to a given recording material by including a transfer unit transfers toner images on an image carrier onto a recording material, a fusing unit fuses toner onto the recording material to the images were transferred, a storage unit stores as processing parameter sets at least either the transfer voltages for the transfer unit or the fusing temperatures for the fusing unit that are set to the optimal values for each type of recording material, a controller operates the transfer unit and the fusing unit using a processing parameter set corresponding to the type of recording material selected from among said processing parameter sets stored and a processing parameter obtaining unit obtains processing parameter sets for recording materials that are not stored in the storage unit and stores them in the storage unit.
