    摘要： A laser scanner control circuit which is used for an apparatus for scanning onto a photo sensitive material by a laser beam and forming and image thereon is constructed as a monolithic driver IC onto a single chip. A reset circuit is provided for a sample-hold circuit so as to minimize the laser power when the image forming apparatus is in a standby mode. A circuit to detect an abnormality of the laser power is further provided. Due to this, the safety of the laser power control of the sample-hold circuit is improved. The operation of the sample-hold circuit can be started at a time point when the laser emitting operation is stable.

    摘要： There is provided a communication system which is capable of resetting sub-communication ICs without providing special reset signal lines for transmitting a reset signal and also capable of properly transmitting a communication reset signal to the sub-communication ICs to reset the same when the system is in an abnormal state or when the power supply is turned off, an image forming apparatus provided with this communication system, an initialization method, and a storage medium that contains a program for executing the method. A host CPU controls the whole communication system. A communication controller controls a serial communication. A plurality of sub-communication ICs transmit serial data between themselves and the communication controller. A first reset IC resets the host CPU, and a second reset IC rests the communication controller. The first and second ICs reset the host CPU and the communication controller, respectively, according to different setting conditions. More specifically, the first reset IC resets the host CPU when the power supply voltage of the communication system is lower than a first predetermined value, and the second reset IC resets the communication controller when the power supply voltage is lower than a second predetermined value that is lower than the first predetermined value.

    摘要： An image heating apparatus capable of compatibly realizing enhancement of durability of a heat rotation member heated by magnetic flux from magnetic flux generation means and early rise up of the image heating apparatus to a heatable temperature includes magnetic flux generation means, heating means, drive means, pressure rotation member, and control means. The control means controls power supply to the magnetic flux generation means and the heating means and rotational drive of the drive means. The control means effects control so that rotational drive of the heat rotation member and the pressure rotation member and power supply to the magnetic flux generation means are stopped until a temperature of the pressure rotation member reaches a predetermined value after power supply to the heating means is effected at the time of startup of the image heating apparatus.
