An image forming apparatus capable of correcting relative position in exposure position between laser beams that scan a photosensitive drum in a scanning direction of the laser beams. A semiconductor laser includes first and second light emitting elements for emitting first and second laser beams. These elements are arranged such that the laser beams expose positions on the photosensitive drum different in the sub scanning direction. A polygon mirror deflects the laser beams to scan the photosensitive drum. Relative position in the scanning direction between images to be formed on the photosensitive drum by exposure by the first and second laser beams is corrected based on correction data. An image data generation section generates drive signals associated with the respective light emitting elements. A semiconductor laser drive circuit causes the semiconductor laser to emit the first and second laser beams, based on the drive signals.

According to an aspect of the invention, a wiring structure includes a pair of printed circuit boards, a cable that connects the pair of printed circuit boards, and a grounding member that causes grounding of the cable in a region including a position separated from a connection end between the printed circuit board and the cable by a distance obtained by dividing a radiation mode length of a system including the cable and the pair of printed circuit boards as antennas by 2.

An image forming apparatus including: a drive motor configured to rotate a rotary polygon mirror to deflect light beam; a signal generation unit configured to generate a rotation synchronous signal; and a rotation control unit configured to control a rotation speed of the rotary polygon mirror, wherein the rotation control unit executes a disabling processing of disabling control of the drive motor based on the rotation synchronous signal, wherein a term of a first disabling processing for a first rotation speed is shorter than a term of a second disabling processing for the second rotation speed, and wherein when the rotation speed of the rotary polygon mirror is changed from the first rotation speed to the second rotation speed, the rotation control unit switches the disabling processing from the first disabling processing to the second disabling processing after reduction of the rotation speed of the rotary polygon mirror is started.

An image forming apparatus includes a polygon mirror having a first mirror surface and a controller. The controller is configured to: acquire a detection interval corresponding to one rotation of a polygon mirror; start scanning exposure with a first beam deflected by the first mirror surface, in response to elapse of a first time period after a detection signal has been detected; and start scanning exposure with a second beam deflected by the first mirror surface, in response to elapse of a second time period after the detection signal has been detected. The second time period is calculated based on the detection interval.

A pressureless high-frequency suspension thermal transfer printer is disclosed, in which a high-frequency signal of 60-100 Hz is generated by a high-frequency switching power supply, and a high-frequency energy conversion motor is driven to convert a signal into high-frequency mechanical vibration which produces 60-100 Hz high-frequency waves which propagate in a longitudinally diffused manner in which an entire transfer printing surface is covered in a direction that is perpendicular to the transfer printing surface, avoiding wasteful loss in the direction of lateral propagation parallel to the transfer printing surface, so that the high-frequency waves act on a molecular movement during the transfer printing process to the greatest extent, which effectively changes a state of the molecular movement, enhances a molecular penetration force, realizes replacement of physical pressure with the high-frequency waves, completely changes a thermal transfer printing process, and achieves pressureless thermal transfer printing.

A process for producing biotech adapters includes ionization of inks that are later used to print on any of a multitude of surfaces while under the influence of specialized electromagnetic radiation, thereby such printing creates the missing frequency that will complete the man-made frequency thus obtaining a bio compatible frequency known to be beneficial to the health of the user. For example, the process is used to print a biotech adapter having an adhesive backing. The biotech adapter is then attached (e.g. by the adhesive) to the user's electronic device (e.g., cellular phone), preferably at a location where such harmful radio waves are emitted in the direction of the user's head. The biotech adapter reacts to the harmful radio waves, completing the missing radio waves by emitting radio waves that are known to be beneficial to humans.
