摘要： A misregistration correcting device includes an image forming unit, a sensor, a reading unit, and a determining unit. The image forming unit form a set of misregistration correcting patterns that includes a reference pattern. The sensors start detecting the set when a predetermined time has elapsed after start of image formation for the first set. The reading unit reads positional information of the set upon detection of the set. The determining unit determines timing to start detecting subsequent sets of misregistration correcting patterns based on positional information of the reference pattern in the first set.

摘要： An image forming method exposes image bearing members by simultaneously reflecting light beams corresponding to different colors by different reflection surfaces of a polygon mirror, transforms electrostatic latent images formed on the image bearing members into toner images for correction, transfers the toner images in an overlapping manner onto a transfer body, and calibrates overlapping positions of the toner images based on an optical detection of the toner images. The toner images are arranged at positions on the transfer body such that the toner images of different colors have no overlap therebetween, even if the toner images shift in a direction perpendicular to the transport direction due to a color registration error. Two first toner images simultaneously formed by two corresponding light beams reflected by one reflection surface of the polygon mirror are arranged adjacent to each other in a transport direction of the transfer body, and are sandwiched by two second toner images simultaneously formed by the two corresponding light beams reflected by the one reflection surface of the polygon mirror along the transport direction.

摘要： A communications apparatus serially transmitting a code string including a target code includes a converter to convert first codes in the code string into second codes having bit strings longer than those of the first codes, and having first polarities and second polarities with a bit string reversed from that of the first polarity, and a transmitter to serially transmit bits of the converted second codes in order from lower-order bits. When the second code includes a number of “0” bits equal to that of “1” bits, the converter converts the second code into a second code having a polarity identical to that of a previously transmitted second code. When the second code includes the number of “0” bits differing from that of “1” bits, the converter converts the second code into a second code having a polarity differing from that of the previously transmitted second code.
