[0057] Figure 8 It is a block diagram of elements involved in the drive control of the paddle 75. Elements having the same functions as those in the first embodiment are designated by the same symbols, and detailed descriptions are omitted. The stirring control unit 114 controls the driving of the paddle 75 based on the number of times the lid 8 is opened and closed.

[0058] Reference figure 1 The cover 8 moves between a closed position that closes the opening 1a of the image forming apparatus 101 and an open position that allows the opening 1a to be opened to allow the user to remove paper jams.

[0059] The switch sensor 96 may also have a push button switch. If the cover 8 moves from the open position to the closed position and the switch is pressed, the switch sensor 96 outputs a signal. The power control unit 113 discriminates the opening and closing of the cover 8 based on the signal output by the switch sensor 96, and switches the power supply level of the power supply u...

Abstract

An image forming apparatus includes: a rotating member to heat a toner on a sheet; a heater to heat the rotating member; a power controller to maintain temperature of the rotating member in a first mode after the temperature reaches the target temperature, and configured to raise the temperature to the target temperature in a second mode after the temperature falls under the target temperature; a waste toner container to store a waste toner; an agitator to agitate the waste toner in the waste toner container; an driver to rotate the agitator a number of times in a drive if the heat controller stops to raise the temperature in the second mode; a counter to count a number of the drives; and an agitation controller to set the number of times in the drive based on the number of the drives.

Description

[0001] Cross reference of related applications [0002] This application claims priority for U.S. Provisional Application No. 61 / 181978 filed on May 28, 2009 and U.S. Provisional Application No. 61 / 183423 filed on June 2, 2009, the entire contents of which are incorporated herein by reference. Technical field [0003] The present invention relates to an image forming apparatus and a control method of a stirring member. Background technique [0004] At present, in the drive control of the stirring member for stirring waste toner, when the image forming apparatus is reset from the power saving mode, or when the cover of the image forming apparatus is switched from the open state to the closed state, the above-mentioned stirring member rotates by a predetermined number of revolutions . [0005] However, in the above-mentioned drive control, the stirring member sometimes rotates unnecessarily. If the stirring member rotates unnecessarily, it causes a waste of electric power. Summary of...
