Abstract:
1. An image forming apparatus, comprising: a photosensitive drum onto which toner adheres in accordance with an electrostatic latent image formed on a surface thereof; a transfer device for transferring the toner adhering on the photosensitive drum onto a recording medium; a fixing device for fixing the toner onto the recording medium; a separation claw for separating the recording medium adhering onto the photosensitive drum; a separation claw fixing frame for fixing the separation claw; a separation claw fixing plate made of a metal, which is fixed between the separation claw and the separation claw fixing frame; a conveyance guide plate arranged opposed to the separation claw fixing frame, the conveyance guide plate being configured to guide the recording medium; and a spur provided on the separation claw fixing frame and fixed on a downstream side with respect to the separation claw in a conveyance direction of the recording medium, the spur being configured to guide the recording medium so as to be conveyed on the conveyance guide plate side and on the fixing device side, wherein the separation claw fixing frame comprises deformation prevention means for preventing deformation of a part fixed to the separation claw fixing plate, wherein the spur has a rotational shaft arranged at such a position that a distance between the rotational shaft and the conveyance guide plate is larger than a distance between the separation claw and the conveyance guide plate, and a distance between a leading end of the spur and the conveyance guide plate is smaller than the distance between the separation claw and the conveyance guide plate, wherein the separation claw comprises a plate made of a resin, the plate being formed to be gradually tapered toward a leading end of a leading end part of the separation claw without changing a thickness, and wherein a fixing position of the separation claw fixing frame is changed to change a position of the separation claw and a position of the spur with respect to one of the photosensitive drum and the conveyance guide plate, to thereby cause the separation claw to abut against the photosensitive drum by a predetermined length from the leading end so as to include a part of the leading end part.
