PURPOSE:To miniaturize the device and to reduce the cost thereof by efficiently compressing developer stored near an image forming part and increasing the quantity of the developer attached on a recording medium. CONSTITUTION:The density of an image can be made dense by partially releasing the winding of a recording sheet 5 with respect to a driving and carrying roller 6a by a guide member 15, regulating the flowing of toner 2 to the image forming part and compressing the toner on the upstream side of the toner carrying direction of a conductor exposure part 1d. Besides, by providing an insulating coating member 1f for interrupting the toner on the tip part of the toner carrying direction of the exposure part 1d, the quantity of the toner attached on the sheet 5 can be increased by reducing a toner resistance value because large pressure is added on a toner storage part. Therefore, the accuracy of the parts such as the roller 6a or a sleeve 3 is not strictly required and the quantity of a gap between the sheet 5 and the exposure part 1d can be increased. Thus, the device is miniaturized and the cost thereof is reduced. |
