An electrostatic charge image developing toner includes a toner particle containing a binder resin, a release agent, a divalent metal, and a trivalent metal, in which the release agent has a domain diameter of 0.5 μm or greater and 1.5 μm or less.

In some examples, a print material apparatus includes a housing having an opening and an inner housing space, and a module removably attached to the housing to cover the opening, the module providing an inner module space that together with the inner housing space define a volume containing a print material of the print material apparatus. The housing is attachable to different modules that provide respective inner module spaces of different sizes for defining different print material containment capacities of the print material apparatus.

A powder storage device includes a container housing and a powder storage. The container housing is configured to allow the powder container to rotate around a rotation axis α. When the powder container is rotated from an installing position to a predetermined position in a peeling-off rotation direction around the rotation axis α, a supply port moves to a position corresponding to a receiving port, a bonder in which the sealer adheres to the powder container is peeled off, and thus the supply port and the receiving port are interconnected.

An image forming apparatus includes plural image forming units and a controller. The plural image forming units are configured to form images of colors using colorants, respectively. The controller is configured to perform control such that the plural images formed by the plural image forming units are output as one image onto a recording medium. At least two of the image forming units are configured to form images using colorants of special colors, respectively and are arranged in succession.

An image forming apparatus includes a conveyer that conveys a recording medium supporting an image; a softener that softens the image; and a powder applicator that applies powder to the surface of the softened image, in which the applied powder adheres to a range that is narrower in a width direction orthogonal to a conveyance direction of the recording medium conveyed by the conveyer than a maximum width of the image to be supported by the recording medium.

An image forming apparatus includes: an image carrier body to be transported; an image forming unit that forms an image on the image carrier body; a change roller that is in contact with an inner peripheral surface of the image carrier body so as to be rotatable around a rotation axis and that is capable of changing an angle of the rotation axis with respect to a width direction of the image carrier body; a flywheel provided at the change roller; and a driving mechanism that applies a driving force for changing an angle of the rotation axis with respect to the width direction to an applied portion that moves together with the change roller. A direction of the driving force applied to the applied portion by the driving mechanism is opposite to a direction in which the applied portion moves due to gravity acting on the flywheel.

An image forming apparatus includes first and second toner containers that respectively contains a non-luminescent toner and a luminescent toner, a first development part provided with the first toner container, and causing the non-luminescent toner, which is supplied from the first toner container, to adhere to a first latent image formed based on image data, a second development part provided with the second toner container, and causing the luminescent toner, which is supplied from the second toner container, to adhere to a second latent image formed based on the image data, which is used for the first latent image, a transfer part that transfers the non-luminescent toner adhering to the first latent image and the luminescent toner adhering to the second latent image to a medium, and a fuser part that fuses the non-luminescent toner and the luminescent toner transferred to the medium.

The image forming apparatus includes a drum cartridge having a photosensitive drum and a drum drive input member; a developing cartridge configured to be movably mounted to the drum cartridge, the developing cartridge comprising a developing roller disposed so as to face the photosensitive drum and a developing drive input member; a drum drive transmission member configured to engage with the drum drive input member and configured to transmit drum driving force to the drum drive input member while permitting a positional gap of the drum drive input member within a predetermined range; and a developing drive transmission member configured to engage with the developing drive input member and configured to transmit developing driving force to the developing drive input member while permitting a positional gap of the developing drive input member within a predetermined range.

An electrostatic charge image developing toner contains toner particles, titanic acid compound particles that are added to an exterior of the toner particles, have a peak existing in a range of 20 nm or more and less than 80 nm in a number-based primary particle size distribution curve, and have an average circularity of 0.88 or more and 0.94 or less, and silica particles that are added to the exterior of the toner particles and have, in a number-based primary particle size distribution curve, a small size-side peak existing in a range of 20 nm or more and less than 80 nm, a large size-side peak existing in a range of 80 nm or more and less than 130 nm, and a valley existing between the small size-side peak and the large size-side peak, in which a difference in a particle size between the peak in the number-based primary particle size distribution curve of the titanic acid compound particles and the small size-side peak in the number-based primary particle size distribution curve of the silica particles is 20 nm or less, and in the number-based primary particle size distribution curve of the silica particles, in a case where the silica particles having a particle size less than the valley are defined as small-sized silica particles, and the silica particles having a particle size equal to or larger than the valley are defined as large-sized silica particles, an average circularity of the small-sized silica particles is 0.88 or more and 0.94 or less.

A recovery container includes: a container body that is attachable to and detachable from an attachment target and capable of accommodating a powder; a first insertion portion that is provided at the container body, is capable of protruding from one of two wall portions of the container body at opposite sides in a direction intersecting an attachment direction of the container body, and is to be inserted into a first opening provided in a portion of the attachment target facing the one of the two wall portions by movement in a protruding direction of the first insertion portion; a second insertion portion that is provided at the container body, is capable of protruding from other of the two wall portions to a side opposite to the first insertion portion, and is to be inserted into a second opening provided in a portion of the attachment target facing the other of the two wall portions by movement in a protruding direction of the second insertion portion; and a third insertion portion that is provided at the container body, is capable of protruding from the other of the two wall portions to a side same as the second insertion portion, and is to be inserted into a third opening provided in a portion of the attachment target facing the other of the two wall portions by movement in a protruding direction of the third insertion portion.
