摘要： An image-forming machine equipped with a transfer device of the type not using a transfer corona discharger is disclosed. A charge supply member is disposed opposite to an image forming member on whose surface a toner image is to be formed, and at a greater distance than the thickness of a transfer material from the image forming member. A voltage of a predetermined polarity is applied to the charge supply member. In a transfer zone, the surface of the transfer material is brought into contact with the surface of the image forming member, while the back of the transfer material is not contacted with the surface of the charge supply member.

摘要： The image-forming machine has an electrostatic latent image-bearing member on which an electrostatic latent image will be formed and an exchangeable developing unit. The developing unit includes a developing housing, a developing agent contained in the developing unit and a developing agent applicator for applying the developing agent onto the surface of the electrostatic latent image-bearing member. A counter is provided that counts the number of times the developing unit has been used and that can be reset. In the developing unit is disposed a developing agent depletion detector that detects the depletion of the developing agent. The developing unit further has a reset that resets the counter when the use of the developing unit is started. When the developing agent depletion detector has detected the depletion of the developing agent, a developing unit exchange signal is formed to indicate that the developing unit be renewed. The developing unit exchange signal is formed even when the counter has counted a predetermined number that corresponds to the life of the developing unit.

摘要： In a time period from the time point where the forward end of a paper sheet fed from a pair of paper separation rollers reaches a registration roller to the time point where the registration roller is driven, when the load torque exerted on a forward roller is not less than second regulated torque, the transmission of power to the forward roller is released by a torque limiter provided for the forward roller. In this case, therefore, the force of paper feeding produced by the pair of paper separation rollers is regulated. Consequently, a suitable force of paper feeding can be applied to the paper sheet, thereby to make it possible to regulate the paper sheet straight in the direction of paper feeding as well as to prevent the paper sheet from continuing to be fed even if the amount of deflection of the paper sheet is saturated between the pair of paper separation rollers and the registration roller to prevent the paper sheet from being wrinkled.

摘要： A developing device supplies developer to an electrostatic latent image bearing body of an image forming apparatus. The developing device includes a container housing with an opening in a position opposite to the electrostatic latent image bearing body and stores developer to be supplied to the electrostatic latent image bearing body. A developing roller is rotatably disposed so that a part of the developing roller is exposed from the opening. A regulator is disposed along an axial direction of the developing roller and has a leading end facing the developing roller to regulate the thickness of developer layer on the developing roller. Two holders support the developing roller and the regulator on the container housing. Each holder includes a developing roller support for supporting an end part of the developing roller and a regulator retainer for retaining the regulator on the container housing.
