    摘要: An image processing apparatus comprises an image data generator and a characteristic converter for converting a characteristic of the image data generated by the image data generator. The characteristic converter includes a table for converting the image data in a first mode and a second table for converting in a second mode. The first and second tables are selectively used in recording one image. Data generator for generating data to be stored in the first and second conversion tables has a reference characteristic conversion table to be used as a base in generating the data.

    摘要: An image forming apparatus has image forming means for forming an unfixed toner image on a recording material, heating and fixing means for heating and fixing the unfixed toner image on the recording material, temperature sensing means for sensing the temperature of the heating and fixing means, and power controlling means for controlling power supplied to the heating and fixing means so that the heating and fixing means keeps a fixable temperature at least on fixing operation based on an output from the temperature sensing means. The power controlling means controls power supply to the heating and fixing means based on the output from the temperature sensing element during the time from receipt of a print signal by the image forming apparatus to performing a heating and fixing process on the recording material so that, in the case where the temperature of the heating and fixing means rises fast, a temperature control operation for keeping the fixable temperature should not be protracted before heating and fixing so as to control excessive rise in the temperature of the pressure member (pressure roller) and prevent a media slip.
