  • Patent number: 11988979
    Abstract: An image forming apparatus comprising: an image bearing member, a developing member that forms a toner image with a toner including a metal soap having a polarity opposite to that of the toner, a supply member that supplies the toner to the developing member, and a control unit that executes a metal soap supply operation of supplying the metal soap from the developing member to the image bearing member when an operation other than the image forming operation is executed, wherein the metal soap supply operation includes a first mode and a second mode, and a potential difference between the supply member and the developing member, which causes an electrostatic force in the direction from the supply member to the developing member to act on the metal soap, is smaller in the metal soap supply operation in the second mode than in the first mode.

    Abstract: Prior art (1) involves a problem that a useless processing is always done even if the user does not use message communication; and prior art (2) involves a problem that the user has to describe a function in a program, and therefore this may be more trouble than prior art (1) and the technical level of the user is required to be high enough to describe the function correctly. A message communication method and device for a programmable controller according to the invention having both advantages of prior arts (1) and (2) and comprising a CPU module and a communication module is characterized in that the transmission parameter of the communication module is defined (Q2), and the user selects (SW) one of the settings: one is such that message communication (S2) is automatically done, and the other is such that the user can describe a function (S3) for message communication.
