Abstract: An image forming apparatus includes a development device, and a control unit that controls the development device. The development device includes a toner collection mechanism having a duct, a filter, and an exhaust fan. The duct is connected to a conveyance chamber of the development container and allows air in the conveyance chamber to flow through. The filter is disposed at a connecting part between the duct and the conveyance chamber, and collects toner flowing into the duct from the conveyance chamber. The exhaust fan makes the air in the conveyance chamber flow to the outside via the duct. The control unit changes rotational frequency or operation frequency of the exhaust fan based on current detected by a current detection unit at non-image forming time.

Abstract: An image forming apparatus includes an image carrier, a cleaning unit, a development device, and a control unit. The development device includes a toner collection mechanism having a developer carrier and a filter. The control unit is capable of executing a scattered toner recovery mode at non-image forming time, in which the filter is vibrated, a potential difference is generated in the direction for the toner to move from the developer carrier to the image carrier, the developer carrier is rotated in a reverse direction to that at image forming time, and the image carrier is rotated in the same direction as that at the image forming time, so that scattered toner, which has dropped from the filter and adhered to the developer carrier, is recovered by the cleaning unit via the image carrier.

Abstract: The image forming apparatus includes: an image carrier, a developing unit, a moving mechanism, and a drive input gear. The developing unit, including a development container and a developer carrier, is supported so as to be swingable among a contact position, a first separate position, and a second separate position. The moving mechanism reciprocates the developing unit between the contact position and the second separate position. The drive input gear inputs, to the developing unit, driving force for driving rotation of the developer carrier. While the developing unit is in the contact position or the first separate position, the drive transmission gear is engaged with the drive input gear. While the developing unit is being moved from the first separate position to the second separate position, the drive transmission gear is separated from the drive input gear.

Abstract: An image forming apparatus includes a plurality of image forming portions, an intermediate transfer belt, a primary transfer member, a secondary transfer roller, a counter roller, and a charge eliminating device. The counter roller is pressed against the secondary transfer roller via an intermediate transfer belt to thereby form a secondary transfer nip portion. The charge eliminating device includes a charge eliminating needle that is disposed with an end part thereof pointing to a downstream side in a conveyance direction of the recording medium, and that is grounded, and a charge eliminating needle protection cover that has a guide surface that is opposed to the recording medium having passed through the secondary transfer nip portion, and that maintains a constant interval between the recording medium and the charge eliminating needle, and eliminates residual charge on the recording medium having passed through the secondary transfer nip portion.

Abstract: A toner container includes a container body, a cap, bosses and a cover. The container body has a toner filling port. The cap is detachable and closes the filling port. The bosses are provided on the container body. The cover is detachably attached to the container body so as to cover the filling port and the bosses, and has a through hole through which each of the bosses penetrates. The boss has a tip end portion protruding from the cover through the through-hole. The tip end portion is provided so as to regulate detachment of the cover by being worked into a head portion having a cross-sectional area larger than the through-hole, and to permit the detachment of the cover by cutting off the head portion. The container body, the cap and the cover can be reused maximum by the number of times corresponding to the number of the bosses.
