Abstract:
1. An image forming apparatus, comprising an image forming section configured to perform operations for irradiating a light beam onto a surface of an image bearing member, forming a toner image corresponding to electrostatic potential changes caused by the light beam and transferring the toner image onto a paper sheet; a control section configured to control the image forming section; and a magnification factor adjusting section configured to adjust image magnification factors of obverse and reverse sides of the paper sheet; wherein the control section conducts controlling operations so as to form a band-shaped toner image on an area located between toner image areas, which reside on the surface of the image bearing member and are adjacent to each other, and the control section employs an index signal based on a detected result of a light beam irradiation, for controlling an operation timing of the image forming section in the toner image area; and wherein, when forming the band-shaped toner image on the area between the toner image areas being adjacent to each other, while controlling the magnification factor adjusting section to implement an operation for adjusting the image magnification factors in parallel, the control section employs a timing signal, created otherwise without depending on the detected result of the light beam irradiation, for controlling the operation timing of the image forming section, and wherein the operation timing controlled by the timing signal is shorter than the operation timing controlled by the index signal.
