Filed: 1990-04-09
Abstract: PURPOSE:To allow carrying the one-component type developer and the transportation thereof to a developing section with simple constitution by attracting a toner onto a sheet uniformly dispersed with permanently magnetize magnetic material particles, thereby transporting the toner. CONSTITUTION:The material of the magnetic particles 8 and the material of a binder resin 12 are mixed and agitated by a heating/agitating/mixing machine 13 to form a slurry-like object 14 consisting of the particles 8 uniformly dispersed in the resin 12. The object 14 is introduced to sheet molding rolls 15 and is molded to the sheet 16. The sheet 16 is then passed in a magnetizing device 17 having magnetizing yokes perpendicularly to the transporting plane of the sheet and the particles 8 dispersed in the sheet are magnetized by controlling the feed speed of the sheet and the magnetizing current in such a manner that the particles generate the same magnetic poles on the surface of the sheet 16. The sheet with which the magnetization is completed is wound on a roller 18 and is fixed to a base body. There is no need for constituting a magnetic field generating member in a developing roll and the one-component developer is transported to the developing section with the simple constitution in this way.

Abstract: PURPOSE: To transport a sheet which lacks firmness and is wavy with creases smoothed out by forcedly making the leading edge of the sheet which is wavy widthwise to the transporting direction lineal and feeding the sheet to a transport roller.  
     CONSTITUTION: The leading edge Sa of a crumbled sheet S is detected by a photo sensor 15, and a solenoid 12 is energized in such a manner as to pivot a pivoting rod 9 on a shaft 8 of an intermittent roller 7 and push up an upper side portion 5a of an endless belt 5 with a push-up roller 11 to move bias. This bias movement forces the sheet S advancing parallel to a guide plate 14 to be inclined, so that the leading edge Sa strikes on the guide plate 14 and the sheet is forcedly bent toward the surface thereof. Whereby the leading edge Sa is forced to be linear, and the sheet is in such a condition transported to a contact portion A between a pair of transport rollers 3, 4. At this time the waviness has been already corrected, so no creases will be caused.
