摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.

摘要： A developing apparatus using a liquid developer and a developing head located to face a path along which a recording medium carrying, for example, an electrostatic latent image thereon is transported. A groove is formed in the surface of the head that faces the transport path. After development, the liquid remaining at the corner defined by the upper inner portion of the groove and the medium is rapidly collected to allow a minimum of smear to occur on the part of the medium which will be transported later. When the transport of the medium should be interrupted during development due to, for example, a jam, the liquid in the groove is collected to prevent a great amount of liquid which would smear a drive roller and other transport members from being transferred from the head to the medium.

摘要： Image forming equipment for performing a predetermined image forming operation by use of a stepwise drive source such as a stepping motor or pulse motor. Either one of a recording medium and a record head is driven by a pulse motor, and whether or not it has reached a predetermined position is determined. While such a decision as to the position of the recording medium or the record head is under way, the displacement per step is changed over to a displacement per step smaller than a displacement to be effected while the predetermined image forming operation is under way.

摘要： An air flow is generated in a space adjacent to the toner control member 3, when an image is not being formed, and also a cleaning electric field for moving the toner away from the toner control member 3 is generated in the same space. For instance, a slit 2a is formed in an outer peripheral section of a cylindrical and rotatable counter electrode member 2, and an air flow generating source 10 such as a fan is connected to the counter electrode member 2. A convex cleaning electrode 11 is formed around the slit 2a of the counter electrode member 2, and a voltage for forming a cleaning electric field is applied from the power supply source for cleaning 8 to this cleaning electrode 11.
