Abstract: A light source control circuit of an optical writing device, admitting connection of light sources and forming an electrostatic latent image on a photosensitive element by controlling a connected light source, includes: a skew correction unit that corrects a skew of a main scanning line of an electrostatic latent image formed by the light source relative to the photosensitive element; a pattern generating unit that outputs image data for forming a predetermined pattern in an electrostatic latent image; a local deviation correction unit that corrects a local deviation of an electrostatic latent image formed by the light source on the main scanning line by acquiring image data processed to form the pattern and by performing a predetermined process; a light source control unit that causes the light source to emit light based on image data in which the local deviation has been corrected; and a setting value input unit.

Abstract: A transferred medium is provided. In one exemplary embodiment a transferred medium includes a projection part projected in a transferring direction. The projection part can be integrally formed at a front end of the transferred medium. The transferred medium can have a plate shape that can be nipped between a feed driving roller that is rotationally driven and a feed driven roller that is rotationally driven in contact with the feed driving roller. The transferred medium can also be configured to be transferred in the transferring direction with the rotation of the feed driving roller. Further, the transferred medium can include a plurality of the projection parts at its front end in a direction perpendicular to the transferring direction of the transferred medium with a predetermined pitch. Other embodiments of a transferred medium are also disclosed.
