Image forming apparatus

摘要

An image forming apparatus is provided that includes an image forming unit including a process unit, a frame configured to hold the process unit detachably attached thereto, the frame including a first communication portion communicating with an outside of the frame in a first direction to detach the image forming unit from the frame, and a second communication portion communicating with the outside of the image forming apparatus in a second direction different from the first direction, and a material holder configured to hold material for image formation by the image forming unit and detachably attached to a predetermined portion of the frame that is close to the second communication portion relative to the voltage output terminal, so as to close the second communication portion.

1. An image forming apparatus comprising:
an image forming unit configured to perform image formation on a sheet, the image forming unit comprising a process unit; a frame configured to hold the process unit detachably attached thereto, the frame comprising:
a first communication portion configured to communicate with an outside of the frame through a first opening that is formed at the frame and open in a first direction, the image forming unit being configured to be detached from the frame through the first communication portion and the first opening; anda second communication portion configured to communicate with the outside of the frame through a second opening of the frame that is separate from the first opening and open in a second direction different from the first direction; a voltage output terminal provided to the frame and configured to apply therethrough a voltage to one or more voltage loads including the image forming unit; a material holder configured to hold material for the image formation by the image forming unit and detachably attach to a predetermined portion of the frame so as to close the second communication portion; a controller configured to:
execute a material-holder detecting process for determining whether the material holder is attached to the predetermined portion of the frame; andexecute a warm-up operation in response to determining that the material holder is attached to the predetermined portion and not execute the warm-up operation in response to determining that the material holder is not attached to the predetermined portion; a cover attached to the frame to be movable between:
an open position where the image forming unit is allowed to be attached to and detached from the frame through the first communication portion; anda closed position to close the first communication portion; and a cover position detector configured to detect whether the cover is in the open position or the closed position, wherein the material holder is configured to be detachably attached to the frame through the first communication portion, and wherein the controller is further configured to perform the material-holder detecting process when the cover position detector detects a positional change of the cover from the open position to the closed position.
