摘要： A sheet material conveying device (60) having a feed roller assembly (62) and a temporary hampering means (64) disposed downstream thereof. The sheet material conveying device includes a driven shaft (134) to be roitated by a driving source and a driven roller (70) mounted thereon. The driven roller has an inside diameter larger than the outside diameter of the driven shaft and is mounted rotatably on the driven shaft. When the forward movement of the sheet material fed by the feed roller assembly is hampered by the temporary hampering means, the rotation of the driven roller is stopped by the resistance of the sheet material exerted on the driven roller in spite of the rotation of the driven shaft.

摘要： A device for use with an image forming apparatus for circulating developer from a cleaning device (8) to a developing device (7) through a circulating passage (13) having a space (40) for allowing a portion of the developer to remain temporarily. The device includes a conveying member (14) for conveying developer in the circulating passage in such a way that developer is moved at a smaller rate in the downstream region thereof than in the upstream region. Supplying means (17a) from the passage (13) into the developing device (7) moves developer at a greater rate than discharging means (33) from the cleaning device (8). The discharging means (33) the the conveying member (14) are driven during operation of the photosensitive drum (4). The supplying means (17a) and means (18) for feeding developer to a developing section of the developing device are interrelatedly driven. The member (17) for supplying developer into the developing device has oppositely directed spiral portions (17a,17b) at its upstream and downstream portions respectively and a plurality of substantially plate-like members (17c) at its intermediate portion. These measures all improve circulation of developer.

摘要： PROBLEM TO BE SOLVED: To provide an original reader which does not cause set-off at the time of reading a double-sided original. SOLUTION: This device is equipped with an original carrying means 24 which reverses a front side and a rear side of an original and feeds the original to an original reading position 4 again after feeding the original to the original reading position 4, an original illumination lamp 6 arranged near the position 4 for irradiating an original face with light, and a shading sheet 5 which is arranged at the original reading position 4 on a rear side of the original and functions as a white plate at the time of shading correction. The shading sheet 5 has a white part 5a and a black part 5b and, at the time of reading a double- sided original, the black part 5b is arranged at the original reading position. Thus, set-off is not caused even if the light of the document illumination lamp 6 is irradiated at the time of reading the double-sided original.

摘要： PURPOSE:To enable the simple and sure conduction of a maintenance operation of a unit by providing an actuation member for setting which actuates an electrostatic charger to a set position in the insertion operation of the unit. CONSTITUTION:A tension coil spring 43j as an energizing member is extended between a top plate part of the electrostatic charging unit CU and a slider 43e of the electrostatic charger 43. The electrostatic charger 43 is held energized to a retreat position at all times by the energizing force of this tension coil spring 43j. Further, the base end of a leaf spring RS as a holding means is screwed to the top plate of the electrostatic charging unit CU and its free end energizes a second projecting part 43g of the slider 43e, thereby maintaining the electrostatic charger 43 at the set position against the energizing force of the tension coil spring 43j. The tension coil spring 43j and the leaf spring Rs energize the electrostatic charger 43 to the retreat position in the side where the insertion of the unit U begins. The electrostatic charger 43 is so energized as to be energized to the set position on the side where the insertion ends.
