    摘要: An image forming apparatus which forms a toner image which is transferred onto a copy sheet includes a fixing unit having a heater for fixing the toner image onto the copy sheet at a predetermined fixing temperature. A cooling unit operates at a first cooling state for cooling the fixing unit. A mode selector is provided for setting a mode of the image forming apparatus to an energy saving mode in which heating operation by the heater is halted. A cooling controller suspends cooling operation of the cooling unit after a delay following a time when the image forming apparatus is set to the energy saving mode.

    摘要: This invention relates to an image forming apparatus of electro-photography type in which a light image obtained by reflected light from an original document image by projecting light onto the original document image is changed in size at a set magnification rate to form an electrostatic latent image on a photosensitive member, and the electrostatic latent image is developed into a toner image. The image forming apparatus includes: a magnification rate setting unit with a lens and a reflective mirror for determining a magnification rate of the light image; lens moving means for moving the lens between a first position and a second position; reflective mirror moving means for moving the reflective mirror between a third position and a fourth position along the optical path; and movement controlling means for controlling the lens moving means to move the lens and the reflective mirror between the first position and the second position and between the third position and the fourth position by respective predetermined distances upon receiving a command signal.
