<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus by which a high control result is attained even by using an encoder whose resolution is physically small. <P>SOLUTION: The image forming apparatus possesses a forming means to form an image on recording paper by forming a latent image on a photoreceptor by exposure and by developing, transferring and fixing it, a moving means used in a transfer process, a driving means to rotate and drive the moving means, the encoder to detect the moving distance information or the moving speed information of the moving means, a calculating means to obtain positional deviation or speed deviation from the output of the encoder, a control means to control a driving source based on an obtained result by performing specified calculation for the position deviation or the speed deviation and a counting means to perform counting by specified cycle T1 in the output interval of the encoder. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
