Patent number: 11970390Abstract: The present disclosure provides a method for producing a microchannel device, which can form a channel that has high hydrophobicity, high solvent resistance as well, and also resistance to heat and damage, on demand with high accuracy, and produces the microchannel device at a low cost, while having high productivity. The method for producing a microchannel device includes: forming a channel pattern from a hydrophobic resin on a porous substrate by an electrophotographic method; melting the channel pattern by heat to allow the channel pattern to permeate into the porous substrate, thereby forming a channel in the inside of the porous substrate.Type: GrantFiled: February 22, 2022Date of Patent: April 30, 2024Assignee: Canon Kabushiki KaishaInventors: Takeshi Yamamoto, Jun Miura, Keiji Miyazaki, Hiroki Tanaka, Makoto Fukatsu, Akihisa Matsukawa, Takayuki Kanazawa, Keigo Mizusawa, Masanori Seki, Masanori Tanaka

Publication number: 20230125722Abstract: An image forming apparatus includes a rotatable image bearing member, a charging member, a developing member, a transfer member, an exposure unit, and a controller. The controller executes a preparatory operation in which before an image forming operation, rotation of the image bearing member is started and a charging voltage and a developing voltage are increased stepwise. In the preparatory operation, the controller carries out control so as to start application of the charging voltage at a voltage value not less than a discharge start voltage of the charging member before a surface region of the image bearing member positioned in a developing portion at a time of a start of the rotation of the image bearing member reaches a charging portion in a state which a surface of the image bearing member is exposed to light by the exposure unit.Type: ApplicationFiled: October 19, 2022Publication date: April 27, 2023Inventors: Shuhei Tokiwa, Takayoshi Kihara, Takayuki Kanazawa, Taichi Sato
