Image forming device having duct for blowing air on charger
First Claim
1. An image-forming device comprising:
- a main casing;
a process casing accommodated in the main casing and removably mounted thereon, the process casing having a casing inlet formed therein;
a photosensitive member that is disposed in the process casing;
a charger that is disposed in the process casing for charging a photosensitive member;
a first duct member that has a duct outlet;
a fan that blows air on the charger through the duct outlet of the first duct member and the casing inlet; and
a duct moving unit that 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,wherein the duct moving unit further comprises an urging member that urges the first duct member in a direction to bring the duct outlet to be positioned near the casing inlet formed in the process casing.

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.
