Abstract: An image forming apparatus is disclosed that is capable of making it simple to initialize a laser system thereof. The image forming apparatus includes a first photo detector that detects a part of a laser beam from each of the lasers and generates respective power adjustment signals for the lasers, a second photo detector that detects another part of the scanning laser beam of each of the lasers and generates a synchronization signal corresponding to each laser, and a power adjustment control unit that changes the output power of each of the lasers to a predetermined value. During the adjustment of output powers of the lasers, the power of a laser is monitored by using the synchronization signal. The power adjustment control unit turns on a laser for power adjustment, and turns off the laser when the scanning synchronization signal is detected twice to complete the power adjustment of the laser, and then starts power adjustment of the next laser.

Abstract: An image forming apparatus shifts a scanning position on a surface scanned of each of a plurality of optical beams in a main scanning direction and a sub-scanning direction, and scans a plurality of lines simultaneously in the main scanning direction by a deflecting part. A synchronization detecting sensor detects the plurality of optical beams. A counting part counts a clock having a higher frequency than a dot clock in an interval between a synchronization detection point of a first beam and a synchronization detection point of a second beam, the first and second beams being included in the optical beams detected by the synchronization detecting sensor. A determining part determines a starting position of writing for each of the plurality of optical beams based on a counted value counted by the counting part. A writing part writes each dot from the starting position of each of the plurality of optical beams determined by the determining part, according to the clock having the higher frequency than the dot clock.

The communication device includes an antenna coil that is arranged on a peripheral part of a housing surface facing a reader-writer of a mobile phone, a magnetic sheet that attracts the magnetic filed transmitted from the reader-writer to the antenna coil, and a communication processing unit that is driven by a current flowing through the antenna coil and communicates with the reader-writer. The magnetic sheet is arranged to be closer to reader-writer than the antenna coil in the central part, and the antenna coil is arranged to be closer to the reader-writer on the outer periphery side, and at least a part of the conductive line of the antenna coil is superimposed in a direction orthogonal to a circuit board.
