ABSTRACT:
A developing device suitable for use in an electrophotographic recording apparatus includes either a toner stirring portion arranged in a toner hopper portion, the toner stirring portion being provided with a portion for varying toner conveying speed, or in the toner a toner stirring and moving means provided in a toner cartridge. A printing irregularity does not occur on a printing paper even if the printing is performed at the state where the amount of toner, which is collected in the toner hopper portion, is too reduced to sufficiently cover the toner hopper stirring portion.
