    摘要: The present invention relates to an image forming apparatus with a developing device in which first and second detecting elements are provided respectively at opposite ends of the device to detect that substantially same amounts of developer are present in both ends. By this, the image forming apparatus is permitted to start image formation only when the developer is evenly dispersed in the both ends of the device.

    摘要: An image forming apparatus which is provided with a sheet guide disposed adjacent to a transfer charger and is movable between the first position adjacent to a photosensitive drum and the second position away from the drum by function of a driver which is controlled by a controller. The controller actuates the driver for positioning the sheet guide at the first position when the rear end of a paper passes the transfer section.The sheet guide disposed between the transfer section and fixing section is movable between the first position where the guide is lifted up from an ordinary paper feed path and the second position which constitutes an ordinary feed path by a function of a driver which is controlled by a controller. The controller actuates the driver for positioning the sheet guide at the first position before the leading end of a transfer paper is nipped by a pair of rollers at the fixing section.
