Abstract

An image forming apparatus includes a housing of an apparatus body, an electrical equipment portion provided to project in a horizontal direction with respect to the housing, wherein a space is provided under the electrical equipment portion, a cover configured to cover the electrical equipment portion, and a louver which comprises plural slats arranged with intervals therebetween and through which an inside of the cover communicates with an outside of the cover, and is provided in a lower surface portion of the cover. The louver comprises a first louver member and a second louver member. The first louver member comprises a first slat portion constituting a part of the slats. The second louver member comprises a second slat portion disposed below the first slat portion to overlap with the first slat portion at least partially in a front view of the louver and constituting another part of the slats.

Dependent claims

An image forming apparatus comprising:

an image forming portion configured to form an image;
a circuit board provided further on a back side of the image forming apparatus than the image forming portion and on which a circuit component configured to drive the image forming portion is implemented;
an apparatus body configured to accommodate the image forming portion and the circuit board;
and
a louver unit through which an inside of the apparatus body communicates with an outside of the apparatus body and which is disposed under the circuit board such that at least a part of the louver unit overlaps with the circuit board when the louver unit is viewed in a vertical direction from underneath, the louver unit comprising a first louver portion and a second louver portion, the first louver portion comprising a plurality of first slat portions arranged with first openings therebetween, the second louver portion comprising a plurality of second slat portions arranged with second openings therebetween,
wherein the apparatus body comprises such a shape that the louver unit and a surface on which the image forming apparatus is installed oppose each other with a space therebetween,
wherein the plurality of second slat portions are disposed under the plurality of first slat portions such that, in a case where the louver unit is viewed in the vertical direction from underneath, the plurality of second slat portions respectively overlap the first openings, and
wherein the first openings and the second openings communicate the inside with the outside of the apparatus body.
