Image Forming Apparatus Having Heating Body, Electric Power Supply, and Controller

摘要

While a continuous conveying process is being executed, a first output process is executed at a timing prior to a prescribed timing, and a second output process is executed for a prescribed period from the prescribed timing. The prescribed timing is prior to a timing at which each recording sheet reaches a heating body. The first output process is for controlling an electric power supply to output electric power to a heat source configured to heat the heating body. The second output process is for controlling the electric power supply to output electric power to the heat source such that an output level of the electric power that is outputted from the electric power supply in the second output process has a tendency to become higher than an output level of the electric power that is outputted from the electric power supply in the first output process.

1. An image forming apparatus comprising:
a heating body configured to thermally fix developing agent onto a recording sheet; a heat source configured to heat the heating body; an electric power supply configured to supply electric power to the heat source; a conveying mechanism configured to convey the recording sheet to the heating body; and a controller configured to control the electric power supply and the conveying mechanism, the controller being configured to perform: executing a continuous conveying process to control the conveying mechanism to continuously convey a plurality of recording sheets in succession to the heating body; while executing the continuous conveying process, executing a first output process at a timing prior to a prescribed timing, the first output process being for controlling the electric power supply to output electric power to the heat source, the prescribed timing being prior to a timing at which each recording sheet reaches the heating body; and while executing the continuous conveying process, executing a second output process for a prescribed period from the prescribed timing, the second output process being for controlling the electric power supply to output electric power to the heat source such that an output level of the electric power that is outputted from the electric power supply in the second output process has a tendency to become higher than an output level of the electric power that is outputted from the electric power supply in the first output process.
