摘要： A partition wall for separating a developing chamber from a toner agitating chamber in an electrostatic developing device includes a high wall portion confronting a toner discharge opening of a toner cartridge, and low wall portions formed on either side of the high wall portion. Toner is discharged from the toner discharge opening of the toner cartridge into the agitating chamber. Toner is then sent over the partition wall and into the developing chamber by rotation of an agitator in the agitating chamber. Toner in the central portion of the agitating chamber goes over the high wall portion, and toner in the side portions of the agitating chamber goes over the low wall portions. Accordingly, a uniform amount of toner is supplied to all points along the length of a developing sleeve in the developing chamber, and hence to all points along the length of a photosensitive drum confronting the developing sleeve.
摘要翻译： 用于将显影室与静电显影装置中的调色剂搅拌室分离的分隔壁包括面对调色剂盒的调色剂排出口的高壁部分和形成在高壁部分两侧的低壁部分。 调色剂从调色剂盒的调色剂排出口排出到搅拌室中。 然后通过搅拌器中的搅拌器的旋转将调色剂送到分隔壁上并进入显影室。 搅拌室中心部分的调色剂越过高壁部分，搅拌室侧部的调色剂越过低壁部分。 因此，将均匀量的调色剂供给到显影室中的显影套筒的长度上的所有点，并因此被提供给沿着与显影套筒相对的感光鼓的长度的所有点。

摘要： A developing unit including a developing chamber provided with a rotatable developing sleeve and a magnet roller capable of rotating inside the developing sleeve, and a first agitator for agitating a developer, and an agitation chamber provided with a second agitator for supplying a magnetic toner to the developing chamber. A restriction member, formed of a magnetic material, is suspended between the developing chamber and the agitation chamber. A free end of the restriction member extends toward the first agitator and a toner supply slit is formed below the lower, or free, end of the restriction member so that the magnetic toner supplied by the second agitator in the agitation chamber is conducted to the first agitator without direct contact with the developing sleeve. As a result, the magnetic toner can be supplied and agitated positively and stably.

摘要： A laser printer is configured to move a pinch roller, provided to a main body casing and operating in a position in which the pinch roller obstructs attachment/detachment of a process cartridge, to a position in which the pinch roller does not obstruct attachment/detachment of the process cartridge. Such a configuration can reduce the number of components of the process cartridge compared with the case of incorporating the pinch roller in the process cartridge. In addition, the configuration can reduce the size of the laser printer since it is unnecessary to attach/detach the process cartridge so as to avoid the pinch roller.
