  • Patent number: 11281136
    Abstract: An image forming apparatus includes a receiving portion to receive an image forming job signal for forming an image on a recording material, an image forming portion to form the image based on the received image forming job signal, and an image heating portion to heat the image, formed on the recording material by the image forming portion, in a nip where the recording material is nipped and fed. An inputting portion inputs a waiting time, and a controller performs an operation in an image forming mode so an image forming operation is not performed until a lapse of the input waiting time from the reception of the image forming job signal, and then the image forming operation is started based on the lapse of the waiting time in a stand-by state in which the image forming apparatus waits for reception of the image forming job signal.

  • Patent number: 10578999
    Abstract: An image forming apparatus includes an image formation unit, an image heating unit, a placement unit, and a control unit. The image heating unit heats an image formed by image formation unit on the recording material that was placed on the placement unit. If an envelope is placed on the placement unit with a flap of the envelope in a direction perpendicular to a conveyance direction of a recording material, the control unit executed control to automatically execute two-sided printing on the envelope such that images formed on a first and a surface of the envelope are heated by the image heating unit. If an envelope is placed on the placement unit with a flap of the envelope in the conveyance direction of the recording material, the control unit executes control to inhibit execution of two-sided printing on the envelope.
