摘要： PROBLEM TO BE SOLVED: To make an image distorsion derived from shift of a photoreceptor belt preventible by forming a reference mark over the whole area on the surface of the photoreceptor belt, and compensating a deviation quantity of the photoreceptor belt based thereon. SOLUTION: In the non-image area on the surface of the photoreceptor belt, a reference straight line (reference mark) 101A is formed over the whole periphery, for instance, by means of printing or the like. A light source irradiating this reference straight line 101 with light is equipped in the vicinity of the photoreceptor belt 101. Then, based on the deviation quantity of the reference straight line detected by detecting means 140, the deviation quantity in the rotary direction of photoreceptor belt supporting rollers 102 to 104 to the photoreceptor 101 is respectively detected and the data thereof are respectively recorded by deviation quantity adjusting means. Write-in of the image data on the photoreceptor belt 101 by the exposing optical system is respectively performed on the position capable of compensating the deviation quantity, based on the deviation quantity data of the photoreceptor belt 101 recorded by the deviation quantity adjusting means.

摘要： PROBLEM TO BE SOLVED: To miniaturize a core while its heat efficiency is retained, thereby miniaturizing a fixing device.
SOLUTION: The fixing device includes: a heat generation member which is conductive; an exciting coil which is disposed facing the peripheral face of the heat generation member and generates heat for the heat generation member by electromagnetic induction; and a core made of a magnetic material which is disposed opposite to the heat generation member with respect to the exciting coil. The surface of the core is formed such that the core has thickness on its internal face where magnetic fluxes passing though the core bend nearly at right angles and with respect to two faces that are nearly at right angles to each other.
