Image forming device
First Claim
1. An image-forming device comprising:
- a main casing;
a process casing accommodated in the main casing and movably mounted thereon, the process casing having a plurality of casing inlets formed therein;
a plurality of photosensitive members that is disposed in the process casing;
a plurality of chargers that is disposed in the process casing for charging the plurality of photosensitive members, respectively;
a plurality of first duct members each having a duct outlet, the plurality of first duct members being in one-to-one correspondence with the plurality of casing inlets;
a fan that blows air on each of the plurality of chargers through the duct outlet of each of the plurality of first duct members and the corresponding casing inlet; and
a duct moving unit that moves the plurality of first duct members between a first position in which the plurality of duct outlets is adjacent to the corresponding casing inlets formed in the process casing, and a second position in which the plurality of duct outlets is separated farther from the corresponding casing inlets than in the first position.

Abstract
An image-forming device includes a main casing, a process casing, a photosensitive member, a charger, a first duct member, a fan, and a duct moving unit. The process casing is accommodated in the main casing and removably mounted thereon. The process casing has a casing inlet formed therein. The photosensitive member is disposed in the process casing. The charger is disposed in the process casing for charging a photosensitive member. The first duct member has a duct outlet. The fan blows air on the charger through the duct outlet of the first duct member and the casing inlet. The duct moving unit moves the first duct member between a first position in which the duct outlet of the first duct member is adjacent to the casing inlet formed in the process casing, and a second position in which the duct outlet is separated farther from the casing inlet than in the first position.
