IMAGE FORMING APPARATUS, IMAGE FORMATION CONTROL METHOD, AND COMPUTER PROGRAM PRODUCT

摘要

An image forming apparatus includes: a fixing unit configured to heat a recording medium on which a recording agent image is formed by an image forming unit, to fix the recording agent image; and a control unit configured to determine, as an image formation start temperature, a temperature of the fixing unit for making the image forming unit start image formation such that a timing at which the recording medium reaches the fixing unit is matched with a timing at which a temperature of the fixing unit is raised to fixing temperature allowing fixing as a result of starting feeding power from an external power supply to a heating unit configured to heat the fixing unit on the basis of a voltage value of the power, and make the image forming unit start image formation when a temperature of the fixing unit reaches the image formation start temperature.

1. An image forming apparatus comprising:
an image forming unit configured to form a recording agent image on a recording medium; a fixing unit configured to heat the recording medium on which the recording agent image is formed by the image forming unit and which is conveyed to the fixing unit, to fix the recording agent image onto the recording medium; a heating unit configured to heat the fixing unit depending on an amount of fed power; a temperature detection unit configured to detect the temperature of the fixing unit; a power supply generation unit configured to generate power for heating to be supplied to the heating unit from power from an external power supply; a voltage detection unit configured to detect a voltage value of the power from the external power supply; and a control unit configured to determine, as an image formation start temperature, a temperature of the fixing unit for making the image forming unit start image formation such that a timing at which the recording medium on which the recording agent image is formed reaches the fixing unit is matched with a timing at which a temperature of the fixing unit is raised to fixing temperature allowing fixing by the fixing unit as a result of starting feeding the power for heating to the heating unit, on the basis of the voltage value of the power from the external power supply, and make the image forming unit start image formation when a temperature of the fixing unit reaches the image formation start temperature.
