摘要： An image forming apparatus having a thermal fixing unit reduces a current inputted from a commercial power source using electric power charged in the capacitive when warming up the thermal fixing unit. The apparatus comprises a first charging unit to charge the capacitive unit at a first charging rate, and a second charging unit to charge the capacitive unit at a second charging rate lower than the first charging rate and greater than a natural power discharge rate of the capacitive unit. A charge switching control unit switches a power source charging the capacitive unit from the first charging unit to the second charging unit when the image forming apparatus transitions into an energy saving standby mode, and returns the power source charging the capacitive unit from the second charging unit to the first charging unit when the image forming apparatus returns from the energy saving standby mode.

摘要： An image forming apparatus includes a feeder means and a recorder. The feeder feeds a sheet of recording paper to a predetermined position in response to a spare paper feed signal instructing the feeding as the sheet of recording paper to the predetermined position preliminarily, and then feeds the sheet of recording paper being stopped at the predetermined position again in response to a record request signal. The recorder records an image on the sheet of recording paper fed by the feeder means through an electrophotographic process. The recorder means starts preparation to execute the electrophotographic process upon receiving the spare paper feed signal. As a results, throughput is increased without causing other problems.

摘要： An image forming apparatus which has an image signal generator for generating an image signal, an image forming unit for forming an image on a recording medium based on the generated image signal, a feeding unit for feeding the medium to the image forming unit, and a controller for outputting different commands to the image forming unit to control the image forming unit. The feeding unit performs spare paper feeding of the medium to a predetermined position before the generator is set in an image signal output enable state and feeds the medium from the predetermined position to the image forming unit after the generator is set in the image signal output enable state. The image forming unit validates a specific command of the different commands when the specific command is received during at least a spare paper feed period from start of spare paper feeding of the recording medium to start of paper feeding from the predetermined position, thereby maximizing the function of the image forming apparatus.
