摘要： A fixing device comprises a thermally fixing roller, a belt, and pushing means which pushes the belt toward the thermally fixing roller. A nipping region is formed between the belt and the thermally fixing roller. A maximum pressure is produced in an upstream end region of the thermally fixing roller in the direction of rotation in the nipping region, another maximum pressure is produced in a downstream end region thereof in the direction of rotation in the nipping region, and a pressure is produced in an intermediate region, which pressure being not higher than the maximum pressure in the upstream end region and not higher than the another maximum pressure in the downstream end region.

摘要： In a clamshell-type image forming apparatus in which the upper unit is rotatably openably connected to the lower unit and in which the upper unit is biased in the opening direction by a biasing member, a hook is disposed at the upper unit and an engagement member is disposed at the lower unit for preventing the upper unit from being opened when the engagement member is engaged with the hook. The engagement of a lock member with the hook in association with the closing operation of a front cover, prevents the hook from being rotated. The disengagement of the lock member from the hook in association with the opening operation of the front cover, allows the hook to be rotated.

摘要： The invention relates to a power transmission mechanism included in the optical system of an image forming apparatus. A power transmission mechanism according to a first mode composes a link mechanism for interlocking the moving member for adjusting the optical path length, in response to the displacement of a lens unit, when changing the magnification factor of the original image. This link mechanism comprises an output unit integrally composed on the lens unit, and a cam member for converting the moving extent of the lens unit by a lever ratio of two cams and transmitting to the moving member. On the other hand, a power transmission mechanism according to a second mode of the invention includes torque transmission mechanism for transmitting a torque alternatively to a scanning mechanism and a magnification varying mechanism. The torque transmission mechanism includes elastic linings to be pressed alternatively to the input members of the scanning mechanism and magnification varying mechanism.
