Abstract:
An image forming apparatus includes: a photoconductor; an optical writer to write a latent image on the photoconductor; an image data generator to generate image data of at least one of text and image and of a correction pattern; a light emission controller to control a light source of the optical writer; a developing device to develop the latent image into a toner image; a transfer device to transfer the toner image onto a recording medium; a fixing device to fix the toner image thereon; a detector to detect the toner image of the correction pattern formed according to the image data; and a writing position controller to control when the light source emits light based on the toner image detected. The correction pattern is formed at each of four corners inside a margin of the recording medium, and includes two edges in each of main scanning and sub-scanning directions.

Claim (Index 1):
An image forming apparatus comprising:\n at least one photoconductor; an optical writer, including a light source configured to emit light, to write an electrostatic latent image on the at least one photoconductor; an image data generator configured to generate image data of at least one of text and image to be printed on a recording medium and image data of a correction pattern for image displacement correction; a light emission controller configured to control the light source to cause the optical writer to form the electrostatic latent image corresponding to the image data generated by the image data generator; a conveyor configured to convey the recording medium; a developing device configured to develop the electrostatic latent image with toner, to form a toner image on the at least one photoconductor; a transfer device configured to transfer the toner image from the at least one photoconductor onto the recording medium conveyed by the conveyor; a fixing device including:\n a fixing rotator configured to press against a surface of the recording medium bearing the toner image; and \n a pressure rotator configured to press against the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which the recording medium is conveyed, \n the fixing device configured to fix the toner image onto the recording medium, the toner image including a toner image of the correction pattern; a detector disposed downstream from the fixing nip in a direction of conveyance of the recording medium to detect the toner image of the correction pattern fixed onto the recording medium; and a writing position controller configured to control a time when the light source emits light to correct a position at which the electrostatic latent image is written on the at least one photoconductor, based on the toner image of the correction pattern detected by the detector, the correction pattern being formed at each of at least four corners inside a margin adjacent to an end portion of the recording medium, the correction pattern including at least two edges in each of a main scanning direction and a sub-scanning direction.
