摘要： A developing apparatus is provided for use in an electrophotographic apparatus. The developing apparatus includes a developer case in which a developer having a mixture of a toner and a carrier is stored, a developing roll which is located in the developer case and which is partially exposed to the outside of the developer case adjacent to a photosensitive drum, a front stirring roll which is located below the developing roll in the developer case to make a flow of developer in the developer case and below the developing roll, a rear stirring roll which is located rearwardly of the front stirring roll in the developer case to create a flow of developer in a direction opposite to the direction of flow of the developer produced by the front stirring roll, and a guide plate located between the front and rear stirring rolls for guiding most of the developer which falls form the developing roll towards the front stirring roll.

摘要： A printer for electrophotographically forming an image on a continuous-form recording paper. The printer has a transfer unit and a pair of heat fixing rollers which are brought into a withdrawn state, in a print stand-by state. Thus, the recording paper is out of contact with a photoconductive drum and a heat roll when the transfer unit and heat fixing rollers are in their withdrawn state. A pair of dust removing brushs are also brought into a withdrawn state in the print stand-by state so as to be out of contact with the recording paper.

摘要： A skewing detection mechanism for a printer of type wherein an image is formed onto a continuous recording form. A pivotally movable sensor is arranged in abutted and biased relation to the continuous recording form being transported along a predetermined transport path. A detector is provided for detecting pivotal movement of the sensor.
